Rampaging Mind

When you deal damage with an instant or sorcery
for the first time on your turn, put a Rampage
counter on Rampaging mind.
When you cast an instant or sorcery spell that
targets a creature, player, or planeswalker,
Rampaging Mind deals damage to that target
equal to to number of Rampage counters on it.
If at the end of your turn you have not cast an
instant or sorcery, remove all Rampage counters
from Rampaging Mind.
