Evolution Witness + Agonasaur Rex + Insidious Roots + Ashnod's Altar + Purphoros, Bronze-Blooded

Evolution Witness

Agonasaur Rex

Insidious Roots

Ashnod's Altar

Purphoros, Bronze-Blooded

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. Insidious Roots triggers, creating a 0/1 Plant creature token, and then putting a +1/+1 counter on each Plant you control.
5. Resolve the Agonasaur Rex ability from step 1, causing you to draw a card.
6. Activate the Plant by tapping it, adding .
7. Activate Ashnod's Altar by sacrificing the tapped Plant, adding CC.
8. Repeat.

This delightful recycling engine relies on a clever recursion loop between Agonasaur Rex and Evolution Witness to continuously cycle your giant dinosaur right back to your hand. Every single iteration is fueled by the mana generated when Ashnod's Altar sacrifices the Plant token birthed by Insidious Roots, which triggers whenever the Agonasaur leaves your graveyard. Meanwhile, Purphoros, Bronze-Blooded stands ready as a legendary enabler whose passive haste and artifact-cheating activation could propel your strategy even further, rounding out a deeply synergistic engine that converts cycling costs into an endless loop of counters, mana, and card draw.
