Ajani's Battle Cry

As an additional cost to casting Ajani's Battle
Cry, scream out a battle cry.
Creatures you control get +4/+4 until end of
turn.
Unintelligent Screaming -- If you revealed and
screamed the names of all the cards in your
opening hand before your first turn, those
creatures instead get +8/-1 and double strike
until end of turn.
