Evolution Witness + Agonasaur Rex + Kheru Goldkeeper + Anointed Procession + Exalted Sunborn

Evolution Witness

Agonasaur Rex

Kheru Goldkeeper

Anointed Procession

Exalted Sunborn

How it works

1. Activate Agonasaur Rex's cycling ability by paying 2 and discarding it.
2. Agonasaur Rex triggers, putting two +1/+1 counters on Evolution Witness.
3. Evolution Witness triggers, returning Agonasaur Rex from your graveyard to your hand.
4. Kheru Goldkeeper triggers, creating four Treasure tokens.
5. Resolve the Agonasaur Rex ability from step 1, causing you to draw a card.
6. Activate three Treasures by tapping and sacrificing them, adding 2.
7. Repeat.

This elegant loop hinges on a clever recycling cycle fueled by Agonasaur Rex's cycling ability, which targets Evolution Witness to place +1/+1 counters on it. Because those counters trigger Evolution Witness, it pulls Agonasaur Rex right back out of your graveyard and into your hand, ready to be cycled all over again. Meanwhile, Kheru Goldkeeper sits watching cards leave your graveyard, generating Treasure tokens to pay for the entire engine. With Anointed Procession and Exalted Sunborn doubling those token creations into a windfall of four Treasures per iteration, you easily net extra mana on every single loop to draw your entire deck, amass near-infinite artifacts, and pump your creatures to astronomical proportions.
