I "intended" to pick tristana

Well it's your fault you don't look what you pick.

Could be worst, at least you have range. The Q will help you duel and the R can work as wards, GLHF.

I actually did do this once... Somehow I picked ChoGath instead of Jinx... hahahahah.. I was pretty embarrassed. :(

This happened to Korean teams a lot in bans back when Ahri was a common ban. They would use the search function and accidently ban Annivia it was great

Well, so long as you didn't purposefully pick Teemo you may be spared the flash-mob.
