Gadroth, Unholy Inquisitor

Flying, trample

Whenever Gadroth, Unholy Inquisitor deals combat damage, target opponent sacrifices a historic permanent they control. If that permanent was a creature, put a +2/+2 counter on Gadroth, Unholy Inquisitor, then double the number of counters on it.

Whenever a historic permanent you control goes to your graveyard, this creature fights target creature
you don't control.
