Well, my fire deck has been working pretty well—5 out of 5. I realize this isn't much testing but I realized I made a mistake. Bolting them to death is okay when they don't have many creatures, but you have 0 chance of winning against a flying weapon deck that has all the rares you want to win! I'm stumped. If I design a deck against the rainbow decks, I can consistently win, but my chances of actually getting a rare is small just because rainbow decks have so many different cards. But if I design a deck to win against those flying weapon decks, then I'm going to lose a lot of money from losing to rainbow decks or forfeiting to find that flying weapon deck. I guess I'll just stick with farming AI3 and hope I'll eventually win a few pulverizers and an eternity.
PS: Maybe we should try to compile a list of all the t50 who use flying weapon decks when they're not playing.
karasoytari is the one I lost too when I realized my mistake. I think turin, cisco, and chival also have rare decks they put up when not playing.
