P.S. Gemini is, I think, in the "Impossible" category. He starts PU'ing his 8/3 spiders with 8 turns left. I don't see a way around that. Each spider is only worth 26 points. If you use all 6 Liquimatters on spiders, you'll only do 156 points of damage, which is 44 short. Massive Dragons are 8/30. You basically have to luck out and get a massive dragon early, then get all your AM and LS cards, and then spam the spiders before turn 8. I don't think it can be done! ???
He can be hard, but definetly not impossible and never ever a skip. His dragons came mostly early when I played him.
For me, Neptune is harder, as you need dragons/crawlers 2/2 (rare), 1/4 (hard in time) or even 0/6 which needs a lucky early AM/LS draw.
But since I don't know what "medium", "hard" a.s.o actually means (win %), I can't say Gemini is hard or medium.
