WUBRG decks are always a little tricky to judge if they're not blatantly powerful right out of the box, and because the theming of this deck is so cool, it feels disruptive to try and make upgrades to it, so it's almost a case of being a precon that you shouldn't upgrade, but yet it desperately needs it
