Coyolzauhui, Deciever

Double Strike, Prowess (Whenever you cast an
instant or sorcery spell, this creature gets +1/+1 until
the end of the turn.)
Whenever Coyolzauhui deals combat damage to
a player, that player exiles a card from their hand
at random. You may cast instand and sorcery
spells exiled this way for as long as they remain
exiled and you may spend mana as though it
were mana of any color to cast them.
