Hailey, Archangel Commander

Flying, Hexproof, Trample
{2}{r}{g}: Creatures you control gain trample,
flying, and haste until end of turn; they also get
+X/+X until the start of your next upkeep,
where X is Hailey's power. Activate this
ability only as a sorcery.
Whenever you cast a spell, put a +1/+1 counter
on Hailey, Archangel Commander. If that spell
was a creature, put two +1/+1 counters on
Hailey, Archangel Commander instead.
