So I've been trying to make SG's rainbow... for just about (at the time of this writing) a week. Then I played a few games against FG's, and found out it's not because It's a bad deck (well maybe it is but it's better to blame yourself than a successful deck) but because of my playing style.
Living with my variation of Lava destroy rushes and grinding AI3's with a ttw average of about 7, I don't know how to play sloowww Rainbows that take like 10 minutes. So with the upgrades (that costed a huuuuge amount of my money) I wanted to create my own rainbow.
Right now, it works vs. AI3 and SOMETIMES AI5, but not always. I want to get it to the point of an FG farm deck. With as little upgrades as possible.
And if an experienced player tells me that's not possible, then I'll just switch
4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 7q5 7q5 7q5 7q5 74b 74b 52n 52n 52n 5uq 5uq 52r 61t 61t 61t 5f8 5f8 5ro 5c6 5c6 5c6 5lf 5lf 5ol
The strategy is to play the Oty's, Boneyard, devour via Oty, RoF, Nightfall, Emphaty Bond, and use Hourglasses to speed up this process. You should play Owl's Eye until late-ish game where you don't want to use the snipe ability because your oty's are strong enough to basically eat everything (The snipe is to weaken enemies like dragons). Blessing is for the Oty's (duh) and you hope to get a bone wall and use RoF.
I'm probably going to add a few more pillars.
EDIT: Done.
Problem is that it is now 40 cards. :/
It is about four turns faster than SG Rainbow though :/
