Spazmatism

Flying, Vigilance
When Spazmatism enters the battlefield if
Retinazer isn't on the battlefield, search your
deck for a card named Spazmatism and put
it on the battlefield.
{p/c}{p/c}: Spazmatism deals 4 damage to target
blocking creature only activate once a turn.
If Spazmatism would die without any +1/+1
counters on it, regenerate it and put 2 +1/+1
counters on it.
