Gnar

Gnar is really strong and at the moment bugged so it will be hard vs him if he gets mega gnar you have more chances to kill him + your ulti is perfect for mega gnar

Teemo

play safe , if he tries to blind you - use "w" and after 6 if you get near him with your Q he's dead

Fiora

just wait till she uses her riposte , after lvl 6 charge in her like a madman ... and don't forget thornmail

Darius

he is very hard ... if you'r not used to play garen i advice you to not even think fighting him .. but if you have bad luck and find yourself on top with him ask for ganks and wait until you get ulti . Never engage low hp unless you are sure you can win

Akali

Easy , very easy .. garen has been made to ravage akali everywhere if she uses her circle to go invisible use your E to harras her

Dr. Mundo

get ignite and dodge his cleaves , after lvl 6 he will regret that he stacked hp :D

Zed

play safe , do not engage till you know you can kill him . When he uses his shadow to get near you use Q and keep your W for his ulti .

Pantheon

with him you must know when to engage and when not to , after thornmail you can go fight him and also make sure you hit him with a basic so his passive won't stop your Q and when he uses his E you must just use shield and spin for win in him

Gangplank

build armor and you win it easy

Jayce

play safe and build armor , after 6 he it's easy win

Volibear

dunno why but he is really hard to fight in lane and it's annowing to have him on top . The one who gets farmed first wins .

Malphite

Same as voli .

Nasus

Fun as hell when he aproches a near death minion to farm his q just hit hi with your q and he will be easy prey

Renekton

after he uses slice'n dice once you use q ,e,w and ulti

Jax

Farm and wait at least till lvl 3 to have one point in your skills , then w,e,q and you win the trades

Wukong

Lee Sin

Silence then BOOOM!!

Mordekaiser

Max your q and destroy his armor with your e while using shield for less dmg :D
