Evolution Witness + Agonasaur Rex + Kheru Goldkeeper + Parallel Lives + Bard, King of Dale

Evolution Witness

Agonasaur Rex

Kheru Goldkeeper

Parallel Lives

Bard, King of Dale

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 intricate loop centers on Evolution Witness, which uses its triggered ability to return Agonasaur Rex to your hand every time Agonasaur Rex’s cycling trigger places +1/+1 counters on it. Because Agonasaur Rex leaving the graveyard also triggers Kheru Goldkeeper, you generate an influx of Treasure tokens that easily pay for the cycling cost. The true power-multiplier comes from Parallel Lives and Bard, King of Dale, whose replacement effects double both the Treasure tokens created and the cards drawn from Agonasaur Rex. This creates a surging cascade of infinite resources, fueling endless card draw and near-infinite mana.
