has really crucial positioning and can do a ton of damage but needs to be played around by teammates so he isn't exactly a standalone hard carry like kat. However he is a super niche pick, is really hard to play, and can carry if is allowed too.
Is so disgustingly strong in the right hands. Just watch Midbeast if you want some proof. High damage, have to work around worked ground, combo is hard to land but it is really rewarding if you can, ult makes you be able to pressure the entire map really easily, just super versatile in general to be honest.
Is probably the most popular of the three but can DPS like none other. If you hit skill shots and want to melt everyone in a team fight single handedly, I'd go cass.
You edited saying you wanted an assassin. Pretty much all the assassin are really popular, so prepare for that! But
and
are probably the most rewarding to put a lot of time into and can all solo carry games.
