Valley of Familiars

When Valley of Familiars leaves the battlefield,
each player sacrifices all Crystals they control.
At the beginning of your endstep, create a 3/3
Crystal creature token that is the color of your
choice. That token enters the battlefield with
your choice of a flying, first strike, double strike,
deathtouch, hexproof, indestructible, lifelink,
menace, reach, trample, or vigilance counter.
The walls of Drannith can't break our bonds.
