Devoid, indestructible (This card has no color)

Whenever another non Beholder permanent enters the battlefield, exile it under Keregog, Collector of Worlds. Keregog gets +2/+2 for each card exiled under it.

Whenever Keregog deals demage to a player, each player reveals their hand. You may choose up to three permanent cards from their hands and put them onto the battlefield under your control.
