“Leblanc is annoying bc she has insane mobility and hard CC which can set up free kills for her jungler by getting hit by even ONE of her chains. Start E in this lane and try to time your E for when she Ws at you lvl one to avoid the damage and get a good chunk on her. Windwall her Es so you don't get CCed and aren't in danger of getting ganked. Try to sit on her W point she she can't go back to it without you getting good damage on her. Build early MR since she does massive burst damage. You can go cleanse in this lane if their jungler has hard CC too but you probably can never kill her in lane unless you take ignite since she is so slippery.”
“Try dodging her W with your E when she Qs, she becomes pretty predictable with her combo rotation. At lvl 6 you can look for more all-ins but make sure to keep your R for the end or you're gonna end up wasting it thanks to her W - R mobility. At 1/2 items you should have the one-shot advantage on her. If they have an ap jgler go Wits End. Mercs fine if they have more cc's.”
“Always take fleet 2nd wind and unflinching against LB. Play around her W and try to never get in situations where she can E you easily. Should always try to freeze at ur tower or you can easily die to ganks with her amazing setup. Eing to the side when she Ws at you is very good to dodge the damage and try to dodge her E with ur increased MS. Never 3rd Q directly into her without any minions infront of you, she will just land E and it will be very painful.”
“ Dodge her E
 Sit in your minions. If she W's: do W, Q + AA. Use more AAs if she doesn't go back.”
“ Leblanc can reliably burst you, and kite you with her W's to the point where you can never kill her. Take Triple Rejuv, hope to survive, and try to effect the map in other ways. ”
“Level 1 I'll poke her with E-AA, after that I'll stick to farming safely with E and staying out of her W range. More often than not I'll find myself behind in this lane, but that's normal. When she goes in, I'll first use the E for the slow and then I'll try to land a Q. If I feel like she bursts me down whenever I step foot in lane, I'll go Lost Chapter into Mercury's Treads into Luden's. In tough scenarios where the enemies have a magic damage jungler and I'm getting camped, I'll get a Banshee's before finishing Luden's. This delays my power spike quite a lot, but then again, so does dying. On the off chance that I get her low on HP and use E to try to finish her off but she uses W to dash away, I'll cast my R towards the original W position, a lot of LeBlanc players will return to it on reflex.”
“Start Doran + 2 Pots if 1) You think you can outplay her and hit your W's to generate a kill at levels 3-5 or 2) You think she will burst you down post 6 (get an extra ring).
Start Corrupting if you think you will not hit your W's (or you will get poked down) and you rely more on wave clear/spammy poke (you will be way more squisher but more durable -- this is recommended if you are sure you will not get hit by CC spells and instantly die).
I honestly consider the LB matchup a fairly easy one because Taliyah E counters her heavily. The first thing you have to keep in mind against a LB is that her W can be predicted, baited and dodged. If you find yourself near the enemy LeBlanc you will certainly expect a W coming from her, so use E to damage at least 25-40% of her hp and Q for the rest. You can easily setup baits and win the lane by making her dash through your E. Every time you see her using W you should also expect an E so sidestep immediately after the W and try to repeat this process in the other direction for the next combos.
If you struggle against LB go for Cleanse/Barrier but I usually go for Ignite, Time Warp Tonic, Dematerializer and 2 Doran Rings. I usually don't buy MR because I tend to get a kill on LB before I need it. After she's 6 you have to bait her ult in order to fight her and win. On Roams always assume she will follow and always assume she has ult (and your team should be aware of that too, ping them!).
You can try to break her double chain combo by using W properly when she W's towards you.”
“She outranges us, has mobility and excessive damage. Our damage is gated around comboing but it's incredibly difficult to do so when LeBlanc is in control.
This match up is extremely dependent on LeBlanc's distortion and your own Scatter the Weak (E).
Early null mantle is a must and hope you land a 100-0 combo.”
“Mercs is a good first item here just like the ahri matchup. ”
“Don't let her proc her Q mark. Dodge chain by staying behind minions or side stepping when no ally minions are around. Take advantage of her if she uses her W as she won't have an escape/gap closer. Play patiently in lane, don't use EW combo if she has W as she will dodge the spin damage. Merc Treads is good vs her chain.”
