How it works

1. Activate Unbridled Growth by sacrificing it.
2. Mazzy triggers, exiling Unbridled Growth and allowing you to cast it from exile until the end of your next turn.
3. Resolve the Unbridled Growth ability, causing you to draw a card.
4. Cast Unbridled Growth from exile by paying 2 life.
5. Aetherflux Reservoir and Defiler of Vigor trigger.
6. Resolve the Aetherflux Reservoir trigger, causing you to gain 1 life for each spell you've cast this turn.
7. Resolve the Defiler of Vigor trigger, putting a +1/+1 counter on each creature you control.
8. Resolve Unbridled Growth, attaching it to any land you control.
9. Repeat.
10. Once you have drawn your deck, you may use the life accumulated to activate Aetherflux Reservoir's ability to deal near-infinite damage to any target(s).
