How far can you get as a Tristana one-trick

Pretty sure you can one trick anything and make it to low diamond as long as you really master your one trick and understand the overall game.

Tristana has enough solo carry/self peel potential to probably get you in to challenger if you are good enough on her. Unlike Kalista, she has a decent chance at getting back into a game if she falls behind and she snowballs much harder.

A bonus for tristana is that she is rarely in the top tier spot so she isn't likely to be changed very often. The downside being that she is popular enough that most people understand how to play against her already.

Supposedly as long as you're good enough you can make it to diamond one tricking anything.
