Whenever you cast an instant or sorcery spell,
you may have it become a copy of target instant or
sorcery spell in your graveyard with equal or lesser
mana value. Do this only once each turn.
Exile an instant or sorcery spell in your
graveyard: the next instant or sorcery spell you
cast this turn gains casualty 2. Activate only once
each turn.
