Alphonse Elric

Vigilance, Magecraft (When you cast an alchemy
spell you either add a (+1/+1) counter on this creature
or have it fight target creature you don't control)
When Alphonse enters the battlefield search your
library or graveyard for a card named Edward
Elric or a Alchemy sorcery spell and put that card
into your hand. You may play that card for half
of it's CMC, rounded down, this turn.
