Vaermina, Nightmare Queen

Indestructible

Whenever you cast an Aura card, put a stun counter on the Aura's target. While it has the Aura attached to it, that creature has -1/-1 and "Whenever this creature dies, create a 0/2 Illusion creature token with 'Whenever this creature blocks a creature, that creature doesn't untap during its controller's next untap step.'."

Illusions and Nightmares you control have Wither and "Whenever this creature attacks, tap target creature and put a stun counter on it."
