At Knifepoint

As long as it's your turn, outlaws you control
have first strike. (Assassins, Mercenaries,
Pirates, Rogues, and Warlocks are outlaws.)
Whenever you commit a crime, create a
1/1 red Mercenary creature token with "{t}:
Target creature you control gets +1/+0 until
end of turn. Activate only as a sorcery." This
ability triggers only once each turn.
