Springheart Nantuko + Selesnya Sanctuary + Archelos, Lagoon Mystic + Wayward Swordtooth

Springheart Nantuko

Selesnya Sanctuary

Archelos, Lagoon Mystic

Wayward Swordtooth

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 Wayward Swordtooth.
5. Because of the additional Wayward Swordtooth token, you can play an additional land this turn.
6. Repeat.

This intricate loop comes together by turning a simple bounceland into a self-sustaining engine. With Archelos, Lagoon Mystic keeping everything entering the battlefield untapped, Selesnya Sanctuary arrives ready to tap for mana before its own bounce trigger forces it back to your hand. Meanwhile, Springheart Nantuko is bestowed upon Wayward Swordtooth, leveraging the constant landfall triggers to pay for token copies of the Swordtooth. Since Wayward Swordtooth also grants you the ability to play additional lands each turn, you have all the land drops you need to keep replaying Selesnya Sanctuary endlessly.
