Phyrexian Vindicator is an excellent back up plan therefore, as basically the only other card in your deck aside from Stuffy Doll that will make a good target for all those spells
Take Terastal Festival, the Japanese version of Prismatic Evolutions
As a side note, this is one of my favorite cards from the Nuclear Fallout Nuclear Fallout is of course best in decks that synergize with rad counters, but the real win comes from how much value you gain from its variable mana value
How would you build it differently
The reason we are not atop the list with magics most powerful card is because it is almost never cast
Almost everything you do is rewarded in some way, as the game hurls booster packs, special cards, gold and mastery orbs at you
