One thing that all 3 of those champions share is their abysmal win rates, so don't worry too much about that.
The nerf on Swain's root hit him pretty hard, and you will have to deal with his mana issues and abysmal auto attack animation as well, but he is still a pain to deal with either way to other laners. The longer the game goes; the more of an unstoppable killing machine he will be. Ev
Is able to perform well, but she has fallen out of favor as of late, but scales exceptionally well as time goes on, since her cool downs get much much shorter.
Win rates for all of them are the same, but I would say Vlad is much more ''in'' right now you could say. It is important that you farm well and play safely in the lane phase though.
I can't give suggestions on others you could try, but I can tell you how they match up.
