Retreat to Coralhelm + Llanowar Scout + Orzhov Basilica

Retreat to Coralhelm

Llanowar Scout

Orzhov Basilica

How it works

1. Activate Llanowar Scout by tapping it, putting Orzhov Basilica from your hand onto the battlefield.
2. When Orzhov Basilica enters the battlefield, it and Retreat to Coralhelm trigger.
3. Resolve the Orzhov Basilica trigger, returning itself from the battlefield to your hand.
4. Resolve the Retreat to Coralhelm trigger, untapping Llanowar Scout.
5. Repeat.

This delightful loop turns a modest Druid scout into a self-contained engine by exploiting the clever self-bouncing nature of bouncelands. When you use Llanowar Scout to drop Orzhov Basilica straight from your hand, the land's entry triggers both its own return clause and Retreat to Coralhelm's landfall ability. By letting Orzhov Basilica pick itself back up to your hand, you ensure a fresh supply of land drops while Retreat to Coralhelm untaps Llanowar Scout to do it all over again.
