Rellana, Twin Moon Knight

Trample
Rellana's base power and toughness are equal
to the number of instant and sorceries you own
in your graveyard and exile.
Whenever Rellana deals combat damage to an opponent, you may cast an instant or sorcery
from your graveyard with mana value less than
or equal to the damage dealt without paying its mana cost. If you do, exile that card.
