Springheart Nantuko + Selesnya Sanctuary + Oracle of Mul Daya + Horizon Explorer

Springheart Nantuko

Selesnya Sanctuary

Oracle of Mul Daya

Horizon Explorer

How it works

1. Play Selesnya Sanctuary. When it enters untapped due to Horizon Explorer, 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 Oracle of Mul Daya.
5. Because of the additional Oracle of Mul Daya token, you can play an additional land this turn.
6. Repeat.

This clever loop lets you turn an ordinary bounce-land into an infinite token generator by leveraging the constant land drops enabled by Oracle of Mul Daya. With Horizon Explorer on the field keeping Selesnya Sanctuary entering untapped instead of its usual slow pace, playing the land triggers both its own bounce ability and Springheart Nantuko's landfall trigger attached to the Oracle. As Selesnya Sanctuary returns safely to your hand to be replayed over and over again, you fund the Nantuko's copy-making cost with the mana tapped from the land itself, rapidly filling your board with an endless army of Oracle copies.
