Zimone and Dina + Abundance + Retreat to Coralhelm + Springheart Nantuko

Zimone and Dina

Abundance

Retreat to Coralhelm

Springheart Nantuko

How it works

1. Activate Zimone and Dina by tapping it and sacrificing another creature, causing you to reveal cards from the top of your library until you reveal a land card, put it into your hand, then put the land onto the battlefield tapped, and repeat this process once if you control at least eight lands.
2. Retreat to Coralhelm and Springheart Nantuko trigger for each land that enters the battlefield this way.
3. Resolve the Retreat to Coralhelm trigger(s), untapping Zimone and Dina.
4. Resolve the Springheart Nantuko trigger(s), choosing not to pay and creating that many creature tokens.
5. Repeat.

This clever engine puts your entire deck's worth of lands onto the battlefield by turning a single sacrifice into a self-sustaining loop. Abundance replaces your normal draws with a guaranteed land, feeding Zimone and Dina's activated ability while letting you completely stack the rest of your library. As those lands enter, Retreat to Coralhelm untaps Zimone and Dina to keep the taps coming, while Springheart Nantuko provides a steady stream of disposable Insect creature tokens to feed the sacrifice cost of Zimone and Dina over and over again.
