Casualty 3. The copy isn't legendary. (As you cast this spell, you may sacrifice a creature with power 3 or greater. When you do, copy this spell. The copy becomes a token.)

Whenever you cast an instant or sorcery spell, if it doesn't target you or a permanent you control, put a +1/+1 counter on Lilith, Dancer of Death.

Whenever a creature dies, draw a card and Lilith deals 1 damage to any target.
