Carniceiro Silumgar

A creature with exploit “exploited that creature” if the controller of the creature's exploit ability sacrificed a creature as the exploit ability resolved.

If Silumgar Scavenger is dealt lethal damage at the same time as another creature you control, it won't receive a counter from its last ability in time to save it.

You can't sacrifice more than one creature to any one exploit ability.

You choose whether to sacrifice a creature and which creature to sacrifice as the exploit ability resolves. A creature can exploit itself.
