Kasumi Goto

Menace, Protection from Instants
When Kasumi Goto enters the battlefield, target opponent reveals their hand. You choose a
nonland card from it, exile that card as long as
Kasumi remains on the battlefield. If the exiled
card is not a creature card, you may cast it as
long as it remains exiled and you may spend
mana as though it were mana of any color to
cast that spell.
