Well, the ranking how easy a god is, mostly depends on you deck. There is no global ranking though, as you noticed, of course there are gods easier to beat as others. Rainbow and Divine Glory are very hard, Seism and Dark Matter are hard - but with the right deck you can get good win percentages against them. Same for Hermes, Obliterator or Scorpio. The other gods mostly depend on the deck - I find Morte quite difficult to face with my deck, too. Chaos Lord or Destiny can be quite unbeatable if they get the right mutants, but are very easy in most cases. Same for rush decks like Ferox or Paradox - fast losses or you'll win. And a Fire Storm combined with a Bone Wall helps a lot, as it does against Fire Queen. Gemini is much easier now that he doesn't wait for his dragons till he PUs, Graviton, Elidnis or Incarnate can be annoying, but there are many ways to beat them. Miracle is still as easy as it was, though it sometimes takes some time till you win.
Of course that's all my opinion, as I said other players with other decks might think quite different.
