Pick up Master Yi mid.
The trick is to pay attention to enemy cooldowns. Master Yi stat checks a lot of midlaners extremely well thanks to his Double Strike and Wuju Style passives, so if you're smart, you can win trades easily by jumping on the enemy while their abilities are on cooldown.
What makes Yi dangerous in mid lane however is his ability to negate and counter virtually every other standard midlaner through Alpha Strike and Meditate. Meditate crashes a burst mage's damage potential to the ground, and because the large majority of mid laners only have hard CC on one of their non-ult abilities, a well timed Alpha Strike can turn an opponent's Stun into a free engage on an enemy who literally can't defend themselves.
Yi also has a really good safety buffer from enemy armor thanks to Wuju Style, and unlike most other off-meta picks, he scales extremely well into the late game, meaning he's not just an early cheese champion, but a legitimate threat to all stages of the game.
