Kinda terrible but I didn't want to spend more time on it. deck challenge: the only creature you can possibly get on the field is a monocolor 1-drop. I interpreted this as a single 4-of. I choose you, Hex Parasite. Illusions of Grandeur + Celestial Convergence is one win condition, with the parasite eating age counters and omen counters. Though I think you still have to pay 2 per turn per illusions, since you can't interrupt the "put a counter then pay" ability midway through. (Right?) Illusions of Grandeur + Donate is another, famous win condition. Hopefully you can pull off a surprise win with Renounce (saccing a ton of things in response to the celestial convergence trigger). (Note that saccing illusions is a bad idea.) The remaining cards provide filtering, control, lifegain, and brokenness. Swarmyard regenerates the parasite. Considered but ruled out: Sorin Markov: gains you life, and wins with convergence if you have >10 life, but too slow and black intensive Sanguine Bond: instawin with Illusions, but too slow and black intensive Gideon Jura: He would be amazing at keeping you alive, but unfortunately breaks the challenge rules since he can become a creature. A whole ton of lifegain+counterspell cards: cool, but I think cheaper counterspells are just going to save more life in the end. Dromar's Charm and Absorb seem fine, though.
