So now that we know everything there is to know about the new megas, can we have a thread to discuss how we might be able to use them competitively?

I really like the look of Mega sceptile and think it might make a great pokemon for doubles, obviously not the best mega to use but a good one at least. I was thinking I could pair it with something like rotom-h and take advantage of discharge spam, plus it learns quick guard which would help with smogonbird, thinking i'd run it with quick guard, dragon pulse, giga drain/leaf storm and something else, maybe a mixed set to take advantage of its decent attack stat.

All megas are welcome for discussion
