Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Genesis Chamber + Aquastrand Spider

Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Genesis Chamber

Aquastrand Spider

How it works

1. Kill Aquastrand Spider.
2. When Aquastrand Spider dies, its persist ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it due to its graft ability.
3. When Aquastrand Spider enters, Genesis Chamber triggers, creating a creature token.
4. When the creature token enters, Aquastrand Spider triggers, moving a +1/+1 counter from it to the creature token. Aquastrand Spider dies as a state-based action due to having 0 toughness.
5. Repeat from step 2.
