How it works
Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
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 four Treasure tokens.
Resolve the Agonasaur Rex ability from step 2, causing you to draw a card.
Activate three Treasures by tapping and sacrificing them, adding 2.
Repeat from step 2
This clever loop turns the cycle of Agonasaur Rex into a self-sustaining engine by utilizing Evolution Witness's triggered ability to pull the dinosaur right back out of your graveyard. Every time Agonasaur Rex cycles, its trigger places +1/+1 counters onto Evolution Witness, which in turn lets you recur the cycling creature. The real magic, however, comes from Kheru Goldkeeper, whose passive trigger rewards you with a Treasure token whenever a card leaves your graveyard—an influx of resources that is exponentially amplified by the token-doubling effects of both Anointed Procession and Kaya, Geist Hunter's minus ability. By cycling the dinosaur and recurring it over and over, you generate a massive wave of Treasures, draw your entire deck, and fuel near-infinite mana to close out the game.
