@Blacky: I'd go with the azu force and gold lax, could be kinda cool.
@soul: yeah, I agree with you on the mejai's thingy. but nevertheless, you could start with it in a ranked game, if you go on 2/0 and the farm/lane advantage on your side. Also depending on your team, if bot or top loses their lane instead, it's probably not a good idea either. It's always risky to go mejais, but if it works out, you probably carry hard.
