Moash, He Who Quiets

When Moash, He Who Quiets enters, each opponent sacrifices a tenth of the creatures they control of their choice, rounded up.
Whenever an opponent sacrifices a creature, put a +1/+1 counter on Moash.

A youth like him, too big and obviously too confident for a darkeyes, had been considered a threat.
