Rocco, Street Chef

Oracle's Vault

Arcbound Reclaimer

Clock of Omens

Lotus Petal

How it works

1. Activate Lotus Petal by sacrificing it, adding one mana of any color.
2. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Lotus Petal from your graveyard onto the top of your library.
3. Activate Oracle's Vault's second ability by tapping it, exiling Lotus Petal from the top of your library with the ability to play it until end of turn without playing its mana cost.
4. Cast Lotus Petal from exile without paying its mana cost.
5. Rocco's second ability triggers, putting a +1/+1 counter on Arcbound Reclaimer and creating a Food token.
6. Activate Clock of Omens by tapping the Food and Lotus Petal, untapping Oracle's Vault.
7. Repeat.
