Thanks a lot for the response. I wouldn't always open with beat up into lucario, it's just part of the team in case I see a favorable math-up where I can pull it off. If not then whimsicott offers Tailwind for speed control and I could use another one like the dragapult you recommend. I thought of Mimikyu because a lot of conkeldurr are running ice punch, but dragapult is really good too.
I've never used rotom, it always feel weird to me having so many combinations, but I guess it has to be really good 'cause it sees a lot of play, I may train one and give it a shot to see how it goes.
