EDHREC This description is appropriately broad because chaos decks come in many different sub-flavors
You can obtain the Dolliv (1-Diamond rarity) card by opening Paldean Wonders from Paldean Wonders set
Its not a bad idea to suspect Agrus Kos, either
I can only think of a handful right now (Djinn Illuminatus, Harness the Storm, Frankie Peanuts, Cloudstone Curio, and Tooth and Nail) and there have been times when Spikes have messed up Tooth and Nail by grabbing some game ending combo or accelerating it off major Urzatron lands or other quick mana ramp, and then use something that prevents it from being countered (like Boseiju, Who Shelters All)
While mechanics always have an impact on gameplay, there arent very many that completely change the way you draft like Learn/Lesson does
Add that to an always-welcome lifelink card with flying, and you can likely make up a lot of that life loss with ease.
