Mindflayer, Eldritch Conqueror

Whenever a creature you control dies, if it would go
to a graveyard, exile it instead. As long as 5 or less creatures are exiled this way, Mindflayer is not a creature.

Mindflayer's power is equal to the total power of creatures exiled with it.

Mindflayer's toughness is equal to the total toughness of creatures exiled with it.
