YES, YES, YES😍 my favourite fiend series requires more fun like this
Caspar
It’s me

I’m here to convince you ta do Fiendsmith
I’m not sure why this new Magical Musketeer link monster would make you set the other card to your opponent’s field. Any ideas or combos would work with this one?
It sets up for the Link 1.
Aside from the Link-1, the Magical Musket spells require you to own a Musketeer, so setting an S/T to the opponent’s backrow will typically just lock it without a Diabellstar or self-pop. Pends aren’t even good and yet they’re still getting hate cards.
Hate is a very strong word for an effect with such a vague and circumstantial purpose
The Link-1’s effect relies on opponent’s cards. So you can use Max going 1xt more consistently.
Their Link 1 (Magical Musketeer Max) has two effects that work better the more spell/traps or monsters opponent controld
Maybe later there will be a card that will block the opponent some way 🤷🏻
That new TCG exclusive I guess?
Love how many people aren’t scrolling down to see that this question has already been answered the exact same way lol
Revendread Slayer lost brother, Caspar
This is actually kinda clever storytelling. In the story Magical Musket’s based on, Caspar introduces Max to the magic bullets that he uses to win the shooting contest. Here, Caspar is used to set up a card on the opponent’s field so that Brave Max can set up turn 1 and add either a spell/trap to hand.
This guy looks like a villain that would show up in a New Mutants comic.
The volume this card is being released with contains the duels
Armed Dragon Rulers Vs. Ryzeal
Artifact Fiendsmith Vs. Dracotail Magistus
Yey
Another generic engine
how is it generic engine, Casper REQUIRES at least one magibullet that’s not a generic engine
I forgot these weren’t called magical musketeer which makes it even more infuriating the “musketeer” archetype got the dumb skyblaster name.
supporting everything BUT Starry knights…
That’s a good thing.
You forgot Iron Chain, no support ever since their 2008 release, lol
Hold on. Is Caspar getting the Evil Eye treatment? Lore?
>LIGHT Fiend
Get out of my head, GET OUT OF MY HEAD!!!
I hope we get more Magical Musketeers cards. I really like them but they just aren’t good yet.
we really need a field card
Yay… Another fuel to the Fiendsmith degeneracy.
Thanks Konami, but we didn’t need it. You can take it back, it’s OK.
Mastermind?
2025 meta is basicaly add 2 no ash GG
For the like, two of you who care about this, this is a reference to the fact that Caspar is one of the antagonists in Der Freischultz, specifically how he attempted to double down on his deal with Zamiel by offering Max’s soul as collateral after having already sold his own.
My man, the entire archetype is based o Der Freischultz
Heheh, it’s actually “Der Freischütz”. x) But I get that the Umlaut isn’t easy and all.
“Materials: 2 monsters, including a LIGHT Fiend monster”
Oh boy…
What set is “YO11”?
Yo mama
Not a set, it’s the promo for the OCG Structures manga.
