Delney, Streetwise Lookout + Mox Amber + Stone Calendar + Dream Stalker

Delney, Streetwise Lookout

Mox Amber

Stone Calendar

Dream Stalker

How it works

1. Cast Mox Amber by paying 0.
2. Activate Mox Amber by tapping it, adding one mana.
3. Cast Dream Stalker by paying one mana.
4. When Dream Stalker enters, it triggers twice due to Delney, returning Mox Amber and Dream Stalker from the battlefield to your hand.
5. Repeat.

This clever loop relies on Stone Calendar to slash Dream Stalker's casting cost down to zero, turning the blue mana-producing Mox Amber into a free engine for endless recursion. When Dream Stalker hits the battlefield, Delney, Streetwise Lookout doubles its entry trigger, allowing you to cleanly scoop both the Mox Amber and the Stalker itself right back to your hand. Because Delney's power-doubling passive keeps the loop cheap and legal for small creatures, you can repeat the process infinitely to rack up an unbound storm count and continuous entry and leaves-the-battlefield triggers.
