Roy Mustang, Flame Alchemist

Whenever you cast a spell, add {r}. Until end
of turn, you don't lose this mana as steps and phases end.

Creatures you control can boast twice during
each of your turns rather than once.

"You were stupid enough to confess and even more stupid to boast. Everything out of your mouth is fuel
on your funeral pyre. So I think I'll start by burning out your tongue."
