Retreat to Coralhelm + Sakura-Tribe Scout + Boros Garrison

Retreat to Coralhelm

Sakura-Tribe Scout

Boros Garrison

How it works

1. Activate Sakura-Tribe Scout by tapping it, putting Boros Garrison from your hand onto the battlefield.
2. When Boros Garrison enters the battlefield, it and Retreat to Coralhelm trigger.
3. Resolve the Boros Garrison trigger, returning itself from the battlefield to your hand.
4. Resolve the Retreat to Coralhelm trigger, untapping Sakura-Tribe Scout.
5. Repeat.

This clever loop centers on the synergy between Sakura-Tribe Scout and Retreat to Coralhelm, turning a simple tap ability into a self-sustaining engine. By using the Scout to drop Boros Garrison directly into play, the land's own enters-the-battlefield trigger immediately bounces it right back to your hand for the next iteration. Meanwhile, Retreat to Coralhelm spots the land drop and provides the exact untap needed to ready Sakura-Tribe Scout for another go, letting you endlessly repeat the cycle to generate infinite landfall triggers.
