In my Roserade team, I replaced Arcanine with Tornadus-I to welcome it back to UU. I think I underestimated its ability to break games in the metagame with an Acrobatics set. I hardly have to Bulk-Up half the time, as most Pokes just get OHKO'd by Flight Gem-boosted Acrobatics on Turn 1. It's sad that Ambipom outspeeds it, though. I didn't want Ambipom to be good against anything on my team, as that is just a sure sign that my team is awful if Ambipom can beat anything on it. That's really my only trouble with AcroNadus, though.
I've seen very little in regards to Meloetta and the others, though. I am currently undergoing some schemes to help the UU tier out, some of which is devising teams for her and Virizion so I get to try out all the new dropdowns and see how effective they are.
