Delney, Streetwise Lookout + Mox Amber + Semblance Anvil + Dream Stalker

Delney, Streetwise Lookout

Mox Amber

Semblance Anvil

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 ingenious engine relies on Semblance Anvil to heavily discount your creatures, allowing Dream Stalker to be cast for a mere single blue mana. Once it hits the board, Delney, Streetwise Lookout steps in to double its entry trigger, letting you effortlessly bounce both Mox Amber and Dream Stalker itself right back to your hand. Meanwhile, Mox Amber serves as your free-flowing mana source, tapping for the exact blue mana needed to replay the loop while benefiting from its legendary status alongside your setup.
