I can’t believe it, we finally got THE ultimate flag as a monster lol
A computer boot-up screen is now a monster?
The Ultimate Flags each carry a hologram flag in their artwork. This is Ace Breaker’s flag.
This certainly makes up for either Ace Breaker or Ace Sword Slash’s requirements, as they normally each need 2 cards in hand (2 monsters for Breaker) to pop an opponent’s card.
The ideal situation is using Ace Sword Slash on turn 2 and then immediately recovering it with this card so you can pop two cards without losing much card advantage.
Unfortunately the LIGHT Machine card pool is restricted to the 3 bosses – two of which are horrible. I hope they make more of these (at least a retrain of Ace Breaker that is treated as such in the hand).
Something tells me, and I hope I’m not wrong, that Ultimate Flag will receive a new Boss Monster in this Pack (although its Slot, JP019, is very confusing since I don’t know if this support is being treated as Anime or Original support)
Not to mention that we should have a Deck made up of “LIGHT Machine monsters with 800 DEF” in this Pack.
It’s not bad, but I’d like to have more concrete support for Ultimate Flag (or at least some cards that allow you to reuse all of its Monsters; after all, most of them are Light Machines with 200 DEF)
If you want to differentiate it from Rush’s Cyber Dragon, you could add the Requirement of having no cards in the Extra Deck.
Yes! Ultimate Flag support!
