How it works
Activate Noose Constrictor by discarding a nonartifact Lhurgoyf card.
Disa the Restless' first ability triggers, putting the discarded Lhurgoyf from your graveyard onto the battlefield.
When the Lhurgoyf enters the battlefield, Cloudstone Curio triggers, returning another nontoken nonartifact Lhurgoyf from the battlefield to your hand.
Resolve the Noose Constrictor ability from step 1, giving it +1/+1 until end of turn.
