Roy, Chaotic Tactician

Skulk
Whenever Roy, Chaotic Tactician deals combat
damage to a player, look at the cards in that
player's hand. You may choose an artifact, instant,
or sorcery from among them and exile it.
You may cast nonland cards exiled with Roy,
Chaotic Tactician and you may spend mana as
though it were mana of any type to cast them.
