(2) When a card or effect is activated in response to the activation of a card or effect (Quick Effect): You can activate 1 of these effects;
● Negate that effect, and if you do, destroy that card.

i thought we were done with generic synchros with generic negates
>Generic
>Needs a Tuner and a Synchro
>Can only be activated as Chain Link 3
We’re not beating the illiteracy allegations bros
This is either a pure protection against opponent’s negations or an answer to cheeky chain-blocking. It’s not really generic and probably will not see serious play because who would be spending synchro materials for what will be in 99% of cases Counter Counter/Called By The Grave on legs?
@VS Enjoyer
I’d say a synchro climbed monster nowadays is the easiest thing to get out granted you can climb to 7, which a ton of decks can and will do. As for the chain link 3, are we really gonna pretend that chain 2 is something that will rarely occur in this game lol. Not to mention you can choose which of the two in the chain you negate, not to mention you can just chain 2 yourself, then chain 3 this onto it. Yeah I’d say pretty generic
@FreeBagooska most obvious case is those yeah but you also have the versatility to chain link 2 yourself with anything and then negate whatever went off which is a crazy versatile tool to have, I’d say a lot of synchro decks would love this as a combo protector/disrupt, the only thing holding this back is its level and whether you have the deckspace for it. Really interesting that it can be a tuner and non-tuner though, seems they want this to be used as a secure mid combo climb
Crispy – What the crap you’re talking about? The second effect is hard once per turn, you cannot chain one bullet point to other.
Bro READ: you can do a chain link 2 yourself with a card you have, then chain link 3 with this monster and negate the chain 1. lmao
@ Crispy: So something like this, yeah?
Chain Link 1: Opponent activates whatever.
Chain Link 2: You respond with Killer Tune Synchro or Playlist, because those are easy as sin to have live.
Chain Link 3: Zaren gets to sit on Chain Link 1 ’til it breaks.
Killer Tune mentioned on the grounds that this is, of course, the generic built for Killer Tune (7 is super easy for them to make via Track Maker, his mats look at Synchros the way Gottoms looks at EARTH Monsters, and his weird condition is explicitly there in case you want to use him to ladder into anything else under the sun he can make in the occasional moments you aren’t Tuner-locked).
@Baroque yep like that, it’s pretty cool how much versatility it has just because of that “choose which chain to disrupt” effect, and that it can respond to any player’s chain 2 effect. Deff intended for Killer Tune but it’s generic enough i can see it fit like a glove in things such as RDA, and probly many others.
OCG doesn’t care about TCG babies that can’t handle negates in the Extra Deck.
@Crispy
A ton of decks? Name 3 bro.
Yazi is a good generic synchro 7, red rose dragon is a good generic synchro 7. No deck in Tier 0 to 3 plays those and they are easier to summon than this. If it’s a tool for Killer tune, RDA and some obscure useless synchro rogue deck the it’s Not generic. Stop coping and take the L.
did yall just realize that this card is a tuner and doesn’t mention non tuners as material. just a “tuner + synchro”? yup, this card is killer tune support, you can make this with a level 5 plus 2 or a 4 + 3. so now killer tune got 2 more generic synchros that can negate ;-;
Read the card.
This card’s negation is not really generic and in fact is pretty limited. You can only activate it as a CL3, which makes it pretty mid.
Two negates sound scary without context. One is a targeting negate and the generic one can only activated when an effect is activated in response to another. Both function like hot red dragon archfiend of the abyss but that’s it.
I will say that things could get scary as we get more boss monsters with these type of synchro material requirements
Does the word “generic” not mean anything anymore? If it’s support that only one archetype can make good use of, it isn’t generic.
the card’s negation is a res negation yeah, it sometimes wont work properly with some decks, but decks like killer tune (AKA decks that like to do quick effect things to mess with the oponent like popping his cards or banishing a card from their extra) can take use of the effect by responding to a oponent’s card effect with those effects. so letting you chain zaren’s effect.
@FreeBagooska
This new synchro is generic due to the material and effect. Sure, you need to use a synchro monster and not all decks can meet the level requirement, but there is no specific type or archetype that is specified. Red seal is a different case because you require a specific tuner
@NightWish
Multiple archetypes can make use of this card. It is just that requring a synchro monster and the levels make it so that it is not something that is really easy to make.
Neat card. The first of it’s kind I think.
Tachyon Transmigration negates everything in the same Chain, that’s the closest I can think of.
Vanity’s Call as well.
This card text says “Don’t negate my negate or I’ll negate your negate of my negate”
Its second effect is more for if you want to negate something, but all you have is like, a target pop or an extension or something. Your opponent normal summons Snake Eye Ash and activates as CL1, you go CL2 activate uhhhhh idk, Circle of the Fire Kings, whatever. Then you can go Zaren CL3 to negate the thing you responded to. So it’s more like it turns another, non-negation effect into a negation.
That’s one thing it can do, NightWish, though I wouldn’t say it’s “more for that” but more that “it can also do that,” given the effect’s flexibility.
For example, another thing it can also work nicely for — that we could just as easily say it was built for — is when your opponent does something like, say, Chain Link 1 Chixiao, Chain Link 2 Mo Ye; instead of being stuck negating Mo Ye like an Ash Blossom would be, Zaren can just grab Chixiao and squeeze ’til he pops.
So, when you think about it, Didus isn’t wrong, since he can either negate a (non-Counter Trap) negate (e.g., responding directly to an Imperm), or negate in spite of a chainblock (as seen above); it’s just also the case that it’s easy enough to leverage the chainblock-ignorer into a more standard negate with a little tomfoolery, though given the deck the fella’s built with in mind it’s best to say that all these things are what he’s built to do, so . . . “Don’t negate my negate or I’ll negate your negate of my negate, and if you don’t I’ll negate you anyway!” seems apt.
Seems goated in killertune, something you can convert the lvl 4 synchro into and you can proc the negate in many ways in that deck without wasting cards
Notably this doesn’t say the Synchro Monster material has to be a non-Tuner, so this could probably see some use in Killer Tune.
Probably? Bruh this is ‘undirect’ supp for Killer Tune. It is made for them. This, along with the last 2 cards from BPRO (the 2 spells) are indirect supp for the 3 themes of the last Deck Build Pack.
Theyve been printing stuff like this for a while now.. where were u ? lol 😛
I think it’s not bad but not great. Honestly, chain link 3 gets hit easier in today’s game than what I think some people realize. Like I said, still not great overall but can have niche application
you can negate cl1 with this by activating any of your other cards as cl2 such as cl1 branded fusion cl2 killer tune synchro cl3 Zaren no? in this situation the killer tune synchro could be chain blocker by something like branded opening for example but you still get the chance to negate the branded opening
@ Trustbruh: That’d be less ‘chain blocking’ with Opening and more just them responding to Synchro with it to stop Zaren from doing his thing, if you’re talking CL1 Fusion CL2 Synchro CL3 Opening? Though I get the thinking, and it does raise an interesting point — Zaren being out might force people to waste stuff specifically to keep him from being able to hit key things.
That being said, @ Charmander, I think this fella’s pretty good honestly, since as Trustbruh pointed out Zaren can be bent into being a more standard omninegate just by activating stuff in response, like using Imperm on something else the opponent controls or flipping MST or even just starting the usual ‘your turn? No, our turn’ malarkey (e.g., I:P).
It’s criminally easy in the deck Zaren’s built for, but even outside of it, well, you say it yourself, Charmander — Chain Link 3 is hit easier these days than some folks realize.
i dont see why you would argue against it being called chain blocking i mean there is no rule that says chain blocking has to be done by trigger effects, its basically just chaining an effect to a thunder dragon effect while thunder dragon titan is on the field which which was always called chain blocking
can’t this turn any quick effect into a negate?
Yeah
RDA will make great use of this card
Ooooh, I didn’t think about it in RDA. Could be a neat little tech for sure, especially if you can find a way to quick synch.
More like Killer Tune. I am sure the next set will be like slop for RDA just like what they did to @ignister
Wow! A dragon! What a surprise!
neat killer tune card. kinda ass otherwise
Diabell, Queen of the White Forest can summon this, also in white forest the level 4 tuners’ quick effects in the GY are a very easy way to make this card into a generic negate (unless of course the opponent also has some generic quick effect to respond with, but even then it applies pressure)
I think this may see play as it is a good alternative to summon when the opponent has no monster on the filed for silvera to book.
We can’t make this Level 11?
Killer Tune can’t make an 11. At least not without burning through resources, and it would not be worth it.
What on earth do you mean “Killer Tune can’t make an 11” — Visas is RIGHT THERE, all you gotta do is Normal Cue, Cue summons Visas Starfrost, and either you make Amritara with Starfrost and a Lv2 (Juke Joint enables a multitude of sins) or you make Remix with Cue + Mix, and then either way you ladder from there into 11; doesn’t strike me as “burning through resources”, either, since all it’s asking for is Cue and a Lv2 Tuner (Mix preferred), which is pretty easy to have handy.
The trick, of course, is . . . you’re not wrong, I don’t think this guy’d be quite so worth it at Lv11. A Lv11 built with Killer Tune in mind would have to do some downright heinous things to be worth the price of admission.
My point is those are effects you had to use to get there. Those are resources you could’ve used on something else. Point was mostly that an 11 would’ve made no sense for this deck, even if the effect was worth it.
If not Killer Tune, then give one for RDA. They’re missing a Level 11.
Obviously, it’s for killer tune, but it is generic enough that plenty of decks will play it, especially since it can be treated as a non-tuner. The only other Synchro like that (I think) is Silent Psychic Magician, and that is psychic support. Really, the main issue with this card is that it is level 7. Is Killer Tune good at getting to level 7?
Criminally good, yep. You’ve got 2 + 5 (Clip or Mix + Red Seal or Remix, with Clip in particular this is easy as sin), 4 + 3 (Track Maker + a Lv3 Tuner, which he can even search on-summon), or in-the-other-direction 3 + 4 (if you’re running Visas Samsara, in which case Cue can search him out immediately and this’ll make Reframing able to kill, to boot, since Samsara’s Starfrost while out or dead).
So not only can Killer Tune make his negate highly flexible while still doing their own stuff, but they can summon him remarkably simply for minimal effort, which is nice.
EDIT: I may be stupid. Forgot for a split moment that this fella needs a Synchro, omit the Visas mention . . . except if one’s being hare-brained and going 1 + 2 + 4 (Veiler + a Clip or Mix + Visas Samsara) by bridging into a different Synchro (so 2 + 5 again -or- doing 1 + 6, even if that’s a waste of a Loudness War).
Worth noting that either this second bullet point effect is some brand new and baroque rulings phenomenon, or it’s only going to be legal to *Negate the effects of the card that was responded to* if that card was on the field.
This IS a generic omninegate. They activate a card, you chain a quick effect (killertune, ip, a continuous trap, any yummy card, etc) and then you chain this to negate whatever they activated. There’s a TON of cards that just have a quick effect like this. So this is essentially a omninegate, even better as in can sometimes negate cards that other omnis can’t stop like dark ruler or ultimate slayer.
It kinda feels like its meant to be used with cards that have the quick effect: do synchro summon on opp turn, lets it negate and be eaten up as material at the same time
The fact this is DARK Dragon seems to hint that Jack will be the cover of the next core set
Absolutely not tho.
It’s also a Level 7 DARK Dragon… Joey as the cover next core set then ?
@Revolver
DARK Dragon Synchro Monsters are like, Jack’s whole thing…
@Snow
Crow ? Kalin ? Both used DARK Dragon synchro Monsters. Revolver, Yuya, ZARC and Rex Goodwin too.
This card have 0 relationship with RDA whatsoever. It’s s generic DARK Dragon synchro monster and nothing else.
We finally got something very similar to Crystal Wing Synchro Dragon’s anime effect.
“Knot”? DARK (bad) Dragon?? owo
This is good for killer tune since it just says synchro monster. Yummy too.
