one piece card game 3 this limited ULTRA DECK -The Three Brothers-

I can easily see it showing up in Ramp decks, Reanimator decks, and everything in between

The former is a boon to typal decks everywhere, and even decks that just make a lot of one specific type of token in the Command Zone, such as Thalisse, Reverent Medium

These stand out immediately and are considered rare because they look like unfinished prototypes

You can let your chosen target attack another player and deal lethal damage to them, then cast Settle in the end of combat step, when those creatures are still considered attacking but after damage has been dealt, to take out two birds with one stone

Those being army producing top end and cheap support creatures

Reminds you of a JoJo Stand in a way, yes
