I read about the challenge in some random deck-thread and started picking life.
Afterwards I read the opener here, started again random.
Got fire and much better results, 10-0 so far. I didn't fight AI3 yet, but with life I had some problems even with AI2 sometimes.
Already won Hematite Golem and Devourer from the spins, no cards in more spins for life.
Let's see how far I can get this.
