Patron of the Moon + Selesnya Sanctuary + Archelos, Lagoon Mystic

Patron of the Moon

Selesnya Sanctuary

Archelos, Lagoon Mystic

How it works

1. Pay 1 to activate Patron of the Moon, putting Selesnya Sanctuary onto the battlefield.
2. Selesnya Sanctuary triggers, targeting itself.
3. With the trigger on the stack, tap Selesnya Sanctuary for .
4. Allow the trigger to resolve, returning Selesnya Sanctuary to your hand.
5. Repeat.

This clever loop is orchestrated by Patron of the Moon, whose activation fee of {1} is easily fueled by the mana generated along the way. The engine hinges on Selesnya Sanctuary entering the battlefield and immediately bouncing itself back to your hand via its own triggered ability, allowing you to continually repeat the process. Meanwhile, Archelos, Lagoon Mystic sits quietly as a pillar of the combo; when properly tapped, its static ability ensures that Selesnya Sanctuary enters the battlefield tapped so that its bounce trigger and mana-tapping sequence can function seamlessly without missing a beat.
