Whenever you attack, target creature gains deathtouch until end of turn.
Whenever one or more creatures you control deal combat damage to a player, create a Treasure token, then look at the top card of that player’s library and exile it face down. You may cast
that card for as long as it remains exiled.

“What good is treasure if I'm alone?”
