permastealth into any lane, avoids conventional ward play.
walks behind enemy laner thatis even or slightly pushed, activates charm mark.
Laner walks towards tower, straight into melee range of evelynn.
Laner flashes away maybe, or attempts to fight, but evelynn E's onto the target, charming them into her while she unloads her entire combo,
charm ends just as evelynn's base combo does, evelynn ults. Removing any interaction in the gank.
You can all this a 'QQ' post, but playing against a slightly decent evelynn deletes so much fun from the game, if you cant put a ward on her camps near your lane then you might as well live in constant fear of a shadow thot doing 60% of your hp on a base combo before she gets a full item.
