Scariest matchups for me as a Gnar player>>>

You're a Gnar main now? You deserve only the worst that life has to offer. You are the scum of the earth. I hope you only face Yasuos, Zeds and Jayce mains who piss on your grave and bang your sister without even paying for dinner first.

...???

Gnar does better vs Yasuo than he does in general. Zed wise, you'll only see that if the enemy picks Zed top, and an assassin who shows up in one specific place is a godsend to Gnar because he can just WRQ him if he ever tries to do something. Or can just run away, since he builds enough bulk to not give a shit.
