Way of the Berserker

I: Search your library for a Berserker card, reveal
it, put it into your hand, then shuffle your
library.
II: Add {r} for each card in your hand. Until end
of turn, this mana doesn't empty from your
mana pool as steps and phases end.
III: At the beginning of combat on this turn, Berserkers you control gain double strike and
haste until end of turn.
