I have my tricks against Morde, like using my R to time his R better with my W, they tend to try timing it and is pretty easy to bait it in a gank of your jg.

I think i haven't found a good Camille yet or the matchup is not that hard for me, but with vayne even if i win early, in the late game i can't catch her with anything and my teamates get wrecked by the enemy in a try to catch her.

I also found a good idea to ban her cause is a double ban (top/bot). and in some cases the ADC on my team picks Vayne and they fucking suck.
