At least you sort of started. Mine isn't even considered a mass deck. (I only have Hyotei and Rikkai with Ryoma and Kamio on the side.) And the same thing happens to me. It's usually after I look at someone's trade pile when offered it, and I look back after and go, "Oh, I wanted that card more. But it'd be rude to ask, so I'll keep this one."

I have three, and I considered myself accomplished. (Why did he have to have blue hair? I would've been fine with Clear only...) I also understand that. I already have KHR and KnB as mass decks, with KnB being a popular mass deck, but I really am considering just doing PoT (only to flinch at the sheer amount of decks), Hamatora (which I am doing, I think, but I haven't made it official), DMMD or Free. (I can just imagine my post being longer than all my other colors posts combined.)
