Measles

Each player loses one life. All creatures get a
-1/-1 counter.
Reverberate 3 - {2}{b}{b} ({2}{b}{b}: Exile this card
from your hand with three wave counters on it.
At the beginning of your upkeep, remove a wave
counter from it. If you do, copy the exiled card.
You may cast this copy without paying its mana cost.)
