Evolution Witness + Agonasaur Rex + Kheru Goldkeeper + Xorn + Exalted Sunborn
How it works
- Activate Agonasaur Rex's cycling ability by paying 2 and discarding it.
- Agonasaur Rex triggers, putting two +1/+1 counters on Evolution Witness.
- Evolution Witness triggers, returning Agonasaur Rex from your graveyard to your hand.
- Kheru Goldkeeper triggers, creating three Treasure tokens.
- Resolve the Agonasaur Rex ability from step 1, causing you to draw a card.
- Activate three Treasures by tapping and sacrificing them, adding 2.
- Repeat.
This clever loop hinges on the relentless recursion of Agonasaur Rex and Evolution Witness, where cycling the dinosaur puts +1/+1 counters on the witness to instantly buy the Rex back into your hand. Meanwhile, Kheru Goldkeeper quietly tracks those cards leaving your graveyard during your turn, spitting out Treasure tokens every single iteration. That's where the multipliers step in to break the economy wide open: Xorn and Exalted Sunborn act as cascading replacement effects that drastically multiply your incoming Treasure generation, turning a modest trio of tokens into an overwhelming surplus. You easily filter that mountain of gold back into more cycling costs, feeding a self-sustaining engine that draws your entire deck while flooding the board with infinite colored mana and artifact triggers.
