Food Chain + Lumra, Bellow of the Woods + Command Beacon + Amulet of Vigor

Food Chain

Lumra, Bellow of the Woods

Command Beacon

Amulet of Vigor

How it works

1. Activate Food Chain by exiling Lumra, adding seven that can only be spent to cast creature spells.
2. Choose to return Lumra to the command zone from exile.
3. Activate Command Beacon's second ability by tapping and sacrificing it, putting Lumra from the command zone into your hand.
4. Cast Lumra by paying 4.
5. When Lumra enters, it triggers, causing you to mill four cards and return all land cards from your graveyard to the battlefield tapped.
6. When the lands enter, Amulet of Vigor trigger that many times, untapping the lands.
7. Repeat.

This ingenious loop turns Food Chain's creature-exiling engine into an infinite mana generator for your commander, Lumra, Bellow of the Woods. By exiling Lumra and choosing to send her to the command zone rather than letting her stay in exile, you can use Command Beacon to effortlessly pluck her back to your hand for recasting. Once you cast her, Amulet of Vigor steps in to instantly untap the avalanche of lands she dredges up from your graveyard, providing the green mana needed to keep the cycle spinning.
