Retreat to Coralhelm + Guildless Commons + Walking Atlas

Retreat to Coralhelm

Guildless Commons

Walking Atlas

How it works

1. Activate Walking Atlas 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 Walking Atlas.
5. Repeat.

This charming loop achieves infinite landfall triggers by exploiting the unique self-bouncing nature of Guildless Commons alongside the untap trigger of Retreat to Coralhelm. When Walking Atlas places Guildless Commons onto the battlefield from your hand, the land's own enter-the-battlefield trigger forces you to return it right back to your hand. Meanwhile, that very same entry satisfies Retreat to Coralhelm's landfall ability, which untaps Walking Atlas so it can immediately replay the land. Because Guildless Commons effortlessly resets itself to your hand every single iteration, this trio forms a self-contained engine that can fuel any landfall-based strategy indefinitely.
