Trample, Vigilance, Exploit

Other creatures you control have exploit.

Whenever a nontoken creature is exploited, exile that creature. Create a token that's a copy of that creature except it has the ability "When this creature dies, gain 5 life, deal 5 damage to an opponent, and create a Hexstone token" and is a artifact in addition to its other types.

Whenever you sacrifice an artifact, deal one damage to an opponent.
