Retreat to Coralhelm + Guildless Commons + Scaled Herbalist

Retreat to Coralhelm

Guildless Commons

Scaled Herbalist

How it works

1. Activate Scaled Herbalist by tapping it, putting Guildless Commons from your hand onto the battlefield.
2. When Guildless Commons enters the battlefield, it and Retreat to Coralhelm trigger.
3. Resolve the Guildless Commons trigger, returning itself from the battlefield to your hand.
4. Resolve the Retreat to Coralhelm trigger, untapping Scaled Herbalist.
5. Repeat.

This clever loop turns a simple tap ability into a self-sustaining engine by exploiting the bounce mechanic of Guildless Commons. When Scaled Herbalist puts the land onto the battlefield, its entry triggers both its own return-to-hand effect and the landfall ability of Retreat to Coralhelm. As Retreat to Coralhelm untaps Scaled Herbalist, you are immediately ready to replay Guildless Commons, creating an infinite loop that endlessly repeats the process and generates infinite landfall triggers.
