So I am a Silver 2 - Silver 1 Kayn main(Not a one-trick. I can play almost every champion well in my elo. Kayn is just my favorite by far and one of the 3 champions I would ever consider one-tricking.)

The mechanics and such I already know are as follows:

Canceling the Q animation with a wall to get back to autoing faster.

Canceling your auto animation with your Q.

Using Q between two walls to give the extra distance to get in the other wall before E runs out.

Using Rift Herald in a wall.

Using your ult's dash out to hop a wall and escape.

Choosing form outside of fountain for more distance with homeguards.

Buy sorc shoes on blue form due to his passive.

Thank you all so much.
