How broken would this all be? I was thinking why not make an entire Blockade of Magic cards that are converted from Shadowverse? If you don't know what Shadowverse is, it's a f2p Hearthstone game but if Hearthstone was anime.
The plainswalkers are walking anime tropes.
Their "crafts" are similar to anime power aesthetics in design and flavor.
Some things are a bit harder to convert than others, but I think the two elements that might make this not worth it is
1: Imagine if every creature has some form of evasion. Be it Flying, Shadow, landwalk, Intimidate... in Shadowverse creatures can choose to attack a creature OR the player. More often than not you'll only attack creatures so they can't attack you, but it's very agro heavy.
2: Evolutions. Best way I could see this in Magic is Transform. Now imagine Transform was easier to do, but based on a very finite resource like tokens the player keeps and can use to activate a transformation.
