Zimone and Dina + Abundance + Retreat to Coralhelm + Nesting Dragon

Zimone and Dina

Abundance

Retreat to Coralhelm

Nesting Dragon

How it works

1. Activate Zimone and Dina by tapping it and sacrificing another creature.
2. If the creature was a Dragon Egg, it triggers when it dies, creating a 2/2 Dragon creature token.
3. Resolve the Zimone and Dina ability, 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.
4. Retreat to Coralhelm and Nesting Dragon trigger for each land that enters the battlefield this way.
5. Resolve the Retreat to Coralhelm trigger(s), untapping Zimone and Dina.
6. Resolve the Nesting Dragon trigger(s), creating that many creature tokens.
7. Repeat.

This loop transforms a modest sacrifice into a cascading avalanche of mana and tokens, anchored by Zimone and Dina's ability to draw cards and ramp lands. Because Abundance replaces those draws with guaranteed land selections, every activation reliably triggers the landfall abilities of both Retreat to Coralhelm and Nesting Dragon. As the lands flood the battlefield, Retreat to Coralhelm untaps Zimone and Dina to fuel the next iteration, while Nesting Dragon supplies a steady supply of Dragon Egg tokens to be sacrificed right back into the engine.
