This was really fun. Again I went with a reanimator base but had to splash blue since Echoing Truth is just too good here. (Thanks HornofAmmon!)
I couldn't find a good breakdown of the rounds so if anyone wants a list here it is:
1. Leyline of the Void - White Green Mill
2. Nether Void - Red Burn
3. Blood Moon - Red Green Dudes
4. Moat - Relentless Rats Deck (lol?)
5. Energy Flux x5 - Black Vampires
6. Mana Flare - Red Green Ramp/Burn
7. Karma x5 - Artifact Only Deck
8. Doubling Season & Awakening Zone - Red Burn
9. All enchantments above - Mirror Match
Like I said, splashed blue and tuned the creatures to best suite the rounds. The islands are really necessary for the Karma round, and also just to get you past the first two rounds.
For the final round, your opponent is a fool. They will eventually play a swamp to reanimate something and die to their own Karma. Otherwise... play first

On my first try the game crashed with ~One Billion Eldrazi Tokens in play before I could deck the AI.
