With proper execution this card can be a life saver
When this creature becomes untapped or you lose control of this creature, exile that creature
For example, if an Elite Inquisitor (a 2/2 with first strike) blocks a Grizzly Bear (a 2/2 with no abilities), the Inquisitor deals damage before the Bear can, so the Bears dies and the Inquisitor survives 3 Vigilance Vigilance is the ability to attack without tapping
Galvanic Iteration only costs two mana, which lets you cast it easily while ensuring you have enough mana for the actual spell you want to cast and copy
It's definitely a more challenging build for me because Faeries aren't really combat-based, which tends to be my favorite win condition
Im curious to see how this one plays out, but expect it to add some interesting decision points as well as politics to games
