Galea supports this game plan perfectly, not only by having solid baseline stats, but by granting access to any Auras and Equipment on top of the library

I've had the most fun with this deck when using Human Torch as the primary Commander, and he's also the card I've struggled the most against, but each of the four Heroes is valuable in their own right, and the fact that all four are always in the deck means you're never far away from some game-changing plays
That could be a card like Davriels Withering, which perpetually gives a creature -1/-2 if that card reduces a creature to 0 toughness or less and sends it to the graveyard, for example, the debuff will remain in effect even if a player is able to bring it back to battlefield (causing it to immediately die again)
With the TCG reintroducing Pokemon ex, it seems likely that The Pokemon Company International sees value in returning to the days when a more 'normal' Blastoise can win the game
