How to counter Leblanc

You can't.

[1] Get MR and health to avoid dying to her early. Some good options:

• Flat MR Glyphs, Scaling Health Seals (Standard rune page against magic damage)
• 

[2] Ward up and call MIAs so that she can't get kills by roaming. This isn't fool-proof and relies on teammates having some map awareness, but this is something you should be doing every game anyways.

[3] Position correctly. If you are a ranged champion and can farm with abilities, you should be able to avoid a decent chunk of her damage (especially if she has to W into range to QE you). If you are a melee champion, you should try to retaliate whenever she attacks you since she has to get into melee-range for a large chunk of her damage).

[4] Don't get caught alone late-game. If you let yourself get picked off, you are at fault (for lack of map awareness, warding, or ability to track your opponents).

If you don't feed her or let her pick people off, she falls off really hard come teamfights.

The best way is to try and avoid her poke and play safe, she drops hard without kills

her W has a long CD. In lane, when you get her to wiff it, harass the fuck out of her, She is among the squishiest champs in the game, and unlike others she doesn't typically build RoA (Siv HD not withstanding) to compensate either.

The easiest way us buy some Mr and farm safely for 15 min, and watch her start galling off without kills

Brand wins every trade against Leblanc unless you get hit by her E. Which is your fault.

As with other champions, you should pick a counter to her. Of course it will be hard when your opponent counterpicks you. In the case you play a champ that is hardountered by lb (i.e. Viktor) you should ban her. When you are able to counterpick her, there are some champions Diana works very well. When the opponent picks lb before me (I am a lb main and know her very well), she is my strongest pick. Diana has her w to counter lb's harrass. After 6 she is easily able to outtrade her. After two items you can burst lb without issues, your burst is aoe, so you won't have problems with her passive. Zed is still a good pick against her, but you have to know how he works (and he is banned very often). When you main Anivia, she is an awesome pick. She has so much utility that lb hardly can do anything. Of course you should have skill with Anivia.

Because you are lvl 21 I would highly recommend Diana. She is easy to play, makes some fun, has good skins and a well teamfighting for an assassin if you manage to play around your ult resets.

You don't let her get fed. You call mia the second you cant see her. If she doesnt get fed she will be a burden to her team.

she mostly uses her W to either close the gap or Poke, if you go all-in she'll use W/Flash to get away. if she uses W first she'll probably either Poke massively or have so much burst that she 2/3 shots you (W+ult+E+Q)

all I know is keep close like a friggin' mosquito or wait until you have alot of burst yourself.

cc? idfk

cc, or for example when i play azir i build a negatron cloak first to eliminate the one shot and then i take exhaust to further stop her kill pressure.

1. play safe (as in don't give her kills, ever)
2. build MR
3. wait till mid/late game

Congrats, you have just make that person's purpose of picking LB kind of useless.

Play Morg easiest win

Hmmmm I'm afraid you can't destroy her no. The best that you can do is go even with this champion. At least most mislaners out scale

-shield negates LB's burst. Diana's all in is better than hers too. If her passive procs when you go in on her, just simply click her, see which clone has items, and ult her again. Bam dead.

There is no counter to LB. She's a champ with zero risk high reward. The best thing is to just ban her.

Pre-6 all of LeBlanc's kit is fairly telegraphed and easy to predict. Respect her level 2 power-spike from her Q -> W (pretend she is like a Blitzcrank, stay out of her zone while baiting her combo, wait for her to get greedy, and punish when she's on cool-down or mispositioned)

Also, remember that because of LeBlanc's clunk-like burst, some champions can stall laning phase by shoving waves under her turret, and making it a farm lane (which does not go in LeBlanc's favor).

Once LeBlanc hits level 6, she will most likely be able to trade safely with you, depending on the matchup. However, at this point you should also be able to clear waves fast, and just like I stated before, push her under turret and force her to use her ultimate to farm. At this point her roaming is the only thing to worry about, which can be handled with some good map awareness and helpful pings to your teammates.

In the Mid-Late game, even without kills LeBlanc can still burst down you or another squishy if you are mispositioned. Respect her burst and mobility, and force her to take more risks into your teammates by staying somewhat grouped.

Hope this helps!

Ban phase.
