MASTER YI, Limits Broken

First Strike
Instants and Sorceries in your hand cost {1} less
to cast.
When you play an instant or sorcery, remove it
from play instead of sending it to the graveyard.
At your upkeep, you may send any number of
your removed instants or sorceries to the
graveyard to give me +X/+0, where X is equal to
the number sent.
