Fracturing Vortex

Fracturing Vortex deals X damage to each
creature, where X is the number of cards in your
hand.
Reverberate 2 - {1}{u}{r} (Rather than cast this card
from your hand, pay {1}{u}{r} and exile it with two
wave counters on it. At the beginning of your upkeep,
remove a wave counter from it. If you do, you may
cast a copy of this card without paying its mana cost.)
