Griffith, Unrecognizable

On your end step, put a -1/-1 counter on Griffith, Unrecognizable unless you sacrifice another creature.
At the beginning of your end step, if it is night, and you control at least 10 other creatures, and you both own and control Griffith, Unrecognizable and an artifact named Crimson Behelit, exile them, then meld them into Femto, Wing of Darkness.
