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.
