Patron of the Moon + Dimir Aqueduct + Horizon Explorer

Patron of the Moon

Dimir Aqueduct

Horizon Explorer

How it works

1. Pay 1 to activate Patron of the Moon, putting Dimir Aqueduct from your hand onto the battlefield untapped due to Horizon Explorer.
2. When Dimir Aqueduct enters, it triggers.
3. Activate Dimir Aqueduct by tapping it, adding two mana.
4. Resolve Dimir Aqueduct's triggered ability, returning it from the battlefield to your hand.
5. Repeat.

This clever loop transforms Patron of the Moon's land-acceleration ability into an infinite mana engine by leaning on a few quiet enablers. Horizon Explorer does the heavy lifting for the pacing, ensuring that Dimir Aqueduct enters the battlefield completely untapped rather than slowing you down. Because Dimir Aqueduct immediately triggers its own bounce clause upon arrival, you can tap it for mana before returning it straight back to your hand to feed the cycle anew.
