Marisa Kirisame

Flying, first strike
Imprint —Whenever an opponent casts an
instant or sorcery spell, exile it as it resolves.
Marisa Kirisame has +1/+0 for each card exiled
this way. You may cast spells exiled this way, and
you may spend mana as though it were mana of
any type to cast them. (Return any spells cast this
way to their owners' graveyards as they resolve)
