Why waste the cash on upgrading cards you know you arn't going to work on fg, But instead attemtp to make a fg farming deck? I notice you problem didn't set on creating a fg deck, but I still don't see the logic of it. Unless your a card freak who already has 6 copys of every upgraded card(Im looking at you jmizzle).
Even though Jmizzle already responded, I like dragons. I have 8 or 9 (don't feel like counting) upgraded decks I run, and most of them are original or partly original. And yes, one of those decks is a modified Jmizzle rainbow I use to farm gods. I also use various builds of QT's fire lance god farmer.
I wouldn't call myself a card freak, though
. I upgrade decks as I think of them, and then post them if there isn't already a similar deck and the deck is fun to use or very good.
But yeah. I actually made this in game, since the way I see it, if I'm going to post a deck it means I think it's really fun or really good, so I feel I should make a commitment to it. If I'm going to suggest it to others, it better be good enough to make in my account, too.
As to miracle, I think that would be an option. I've also started running it without the light dragon and 5 dials upped, instead. Basically, the build I posted isn't the only build that would work. It is, after all, a rainbow deck.
