Mazzy, Truesword Paladin + Unbridled Growth + Defiler of Vigor + Dawnhart Geist

Mazzy, Truesword Paladin

Unbridled Growth

Defiler of Vigor

Dawnhart Geist

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. Dawnhart Geist and Defiler of Vigor trigger.
6. Resolve the Defiler of Vigor trigger, putting a +1/+1 counter on each creature you control.
7. Resolve the Dawnhart Geist trigger, causing you to gain two life.
8. Resolve Unbridled Growth, attaching it to any land you control.
9. Repeat.

By constantly cycling Unbridled Growth through your graveyard with the exile-and-cast trigger of Mazzy, Truesword Paladin, you turn a humble one-mana enchantment into an infinite engine. Defiler of Vigor provides the cost reduction to cast the Aura for free (paying 2 life instead) while simultaneously growing your board with +1/+1 counters every time the spell is cast. Meanwhile, Dawnhart Geist happily pads your life total with every iteration, letting you comfortably sustain the life payments needed to fuel the Defiler's discount as you draw your entire deck.
