Bonclaw, the Bandit King

Whenever one or more outlaws you control deal
combat damage to a player, exile a card at random
from their hand. You may look at, cast spells and
play lands from among the exiled cards, and you
may spend mana as though it were any type of
mana to cast them.

Creatures you control but don't own, are Assassins
in addition to their other type.
