Springheart Nantuko + Selesnya Sanctuary + Dryad of the Ilysian Grove + Archelos, Lagoon Mystic

Springheart Nantuko

Selesnya Sanctuary

Dryad of the Ilysian Grove

Archelos, Lagoon Mystic

How it works

1. Play Selesnya Sanctuary. When it enters untapped due to Archelos, Selesnya Sanctuary and Springheart Nantuko trigger.
2. Holding priority, activate Selesnya Sanctuary by tapping it, adding .
3. Resolve the Selesnya Sanctuary trigger, returning it from the battlefield to your hand.
4. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Dryad of the Ilysian Grove.
5. Because of the additional Dryad of the Ilysian Grove token, you can play an additional land this turn.
6. Repeat.

This intricate loop is made possible by Archelos, Lagoon Mystic, whose static ability forces incoming lands to enter untapped, turning Selesnya Sanctuary's usual drawback into an explosive advantage. When Selesnya Sanctuary enters the battlefield, it triggers its own bounce ability while simultaneously fueling Springheart Nantuko's landfall ability, which lets you pay the mana generated by tapping Selesnya Sanctuary to copy Dryad of the Ilysian Grove. Because Dryad of the Ilysian Grove grants you an additional land drop on each of your turns, you can continuously replay the returned Selesnya Sanctuary to endlessly repeat the process, generating an infinite army of creature tokens and endless enters-the-battlefield triggers.
