Toph, Greatest Earthbender + Ashaya, Soul of the Wild + Wispweaver Angel

Toph, Greatest Earthbender

Ashaya, Soul of the Wild

Wispweaver Angel

How it works

1. Cast Wispweaver Angel by paying its mana cost.
2. When Wispweaver Angel enters, it triggers, blinking Toph.
3. When Toph enters, it triggers, earthbending Wispweaver Angel as it's a land due to Ashaya.
4. Since zero mana was spent to cast Toph, Wispweaver Angel becomes a 0/0 creature and dies as a state-based action due to having 0 toughness.
5. Toph triggers, returning Wispweaver Angel from your graveyard to the battlefield.
6. Repeat from step 2.
