I agree, unless people get heavy PvP pieces (immo/golem, gotp/nightmare, or other nasty deck pieces) then it doesn't make much sense to not run the rainBro deck. I made a rainbow deck on day 1 with skeleton and went 10-4. Day 2 I got puffer fish and used the same deck but with the new card and went 17-8. BH, steal, deflag, SoG, Sanc, hourglass. I never played it myself, but I bet it just denied people and decked them, maybe the skeletons or fish slowly killed them? Anyways, I really regret this trend or my partaking in it. Today I got soul catcher and made some silly immo death hybrid. I doubt it will go 2:1 on wins, but the rainBro decks get old fast.
