Difficult Customer

Flying, lifelink
Whenever Difficult Customer attacks, it gets
+3/+0 until end of turn unless defending player
exiles a nonland card from their hand. Until end
of turn, you may cast cards exiled this way, and
you may spend mana as though it were mana of
any color to cast those spells.
On that day, Kathy regretted having taken that
promotion to store manager six months prior.
