Amulet of Vigor + Nuka-Cola Vending Machine + Gourmand's Talent

Amulet of Vigor

Nuka-Cola Vending Machine

Gourmand's Talent

How it works

1. If you control a Treasure, activate it by sacrificing it, adding one mana of any color. If you don't control a Treasure, activate another artifact by paying 2, tapping and sacrificing it.
2. Nuka-Cola Vending Machine triggers, creating a tapped Treasure token that is also a Food due to Gourmand's Talent.
3. When the Treasure enters the battlefield, Amulet of Vigor triggers, untapping the Treasure.
4. If needed, resolve the ability from step 1, causing you to gain 3 life.
5. Repeat.
