Trynd or Jax

I'd say Trynd tho. A lot of people counter his fairly easily, but, once you get into mid game and start having top to yourself you'll take a turret each time your opponent leaves lane. You can win the game simply by never leaving top lane lol

either of them if you like playing against teemo/malphite/gnar all day long

speaking from personal experience

serious though, they're not that different from each other, just play them and see which one feels natural, they all 3 get hardcountered so hard you will have to learn how to play losing matchups

watch some boxerpete to get a feel for trynd matchups, and watch hashinshin for jax matchups

why are people even downvoting this wtf

Well, if your parents died in a car crash, I'd recommend Trynd, because his disgusting, unfair, cancerous ult will always put a smile on your face.

If you want someone who's good at not dying in REASONABLE ways, I'd go with Jax.

If you like just spanking people a whole lot, Yi is up your alley.
