i win 4 out of 9 games with an almost completly upgraded rainbow deck, so those odds arent that bad.
This is the issue at hand. If it takes 1500 coins to upgrade a card, and there's a minimum of 30 cards in a deck, that's 450,000 coins to even put up a fight.
I heard so much positive talk about how awesome a FFQ deck was that I decided to make one, and granted it rapes when it gets going.
However in a fight against a god, I'm dead before I can do maybe 25 damage.
Must say I love your maths. Haha
Anyways, scaredgirl's deck may have a decent win percentage but I do not care for that. I care for wins/time. I have tried it upgraded and it is not so good in terms of that. I would even choose mono-aether over that as although you would 'lose' a lot, you just forfeit to Rainbow, Scorpio, Hermes, Graviton and Gemini. So basically you will lose 5/9 and also a bit of the 4/9 so you'll maybe win a bit more than 1/3 of the time but take up 4/9 of the time. Much more effective imo.
