Lulu

ardent rush, her abilities are defensive and offensive. Legit best pick, can even save by using w on enemy champ, if you get hooked

Brand

if he can provide you safe during lane, then brand is a great pick

Thresh

thresh is good for getting kills, but not winning the game, so not perfect

Morgana

her shields can legit win you games

Braum

can't say he is good in low elo

Yuumi

you are rushing for 20 minute win, so don't expect mana hungry yuumi to be very useful

Soraka

idk it's fine for harassment

Lux

will touch farm with e or even q, but a fine pick when you want to have passive farm, at cost of not having a freezed lane, but be aware of junglers, better pick brand or morg instead of her

Nautilus

Janna

just a weak pick

Nami

another weak pick

Karma

weak pick

Zilean

might look like a good idea, but nope

Pyke

bad pykes(and that's what happens in low elo) will make you lose your lane Example: hooking lvl 6 ashe against ashe+morg lane. Might ult for shutdowns and you want to get 500 gold instead of 300g

Blitzcrank

another adc killer

Rakan

agressive lane.

Sona

nope

Leona

pls no

Taric

nope
