Slaanesh, Prince of Pleasure

Indestructible
As long as you control fewer than 5 demons, Slaanesh isn't a creature.
Eminence — As long as Slaanesh is in the command zone or on the battlefield,
Demon creatures you control get +1/+1 for each card in your hand above the seventh.
Whenever you draw a card except the first one you
draw in your draw step, put a +1/+1 counter
on target Demon you control.
