Vilgax

Eminence - Whenever a player attacks with any
number of creatures, Vilgax gets +2/+2 until end of
turn, then create a 2/2 colorless Drone artifact
creature token with flying.

{3}, {t}: Vilgax fights another target creature. If that
creature is destroyed this way, untap Vilgax.
Activate only once each turn.

Whenever Vilgax destroys a creature he gets a +1/+1 counter.
