LeBlanc can deal with teams that have high damage and range.⁴

• LeBlanc can escape with a dash or invisibility.⁵
• LeBlanc can fall off after the first four rounds against health stacking, shields, and crowd control.⁶
• With Deceive and maxed-out Mirror Mirage, LeBlanc's clones explode for 25% maximum health true damage; the explosions might also damage her team through Renata's ultimate.⁷
• Mirror Image creates four clones when its health trigger activates; at max level, the clones gain your augments and their basic attacks deal 20% damage.⁸ Patch unknown
• LeBlanc's clones from Now You See Me may cause a one-round gold gain, but the cause is uncertain.⁹
• LeBlanc's W combined with Blitzcrank's pull is fun with Autocast augments.¹⁰
• With Now You See Me, Earthwake, Augmented Power, and Dashing, LeBlanc can have a fun game.¹¹
• Energized builds are a favorite for mobile poke champions such as LeBlanc.¹²

Since patch 26.16, LeBlanc's passive cooldown is 5 seconds, and Q's base damage is 105–205.³

Earlier formats

• LeBlanc can only thrive if every other team is very squishy.¹⁵ 8x2 duos
• LeBlanc can lack damage against tanks, and fighter champions can have enough survivability to burn her down; missing an ability can be costly.¹⁶ 8x2 duos
• QRQWE with decent augments can almost instantly disintegrate any non-tank or bruiser; landing E during the combo lets LeBlanc kite efficiently.¹⁷ 8x2 duos
• LeBlanc can win with a lot of magic penetration; try Emblem of Ascension.¹⁸ 8x2 duos
• LeBlanc's W made her vulnerable to damage, and her two damaging abilities had narrow hitboxes.¹⁹²⁰ 8x2 duos
• A combo of Q, R, Q, W, E with decent augments could deal heavy damage to non-tanks or bruisers.¹⁷ 8x2 duos
• The Kinkou Jitte is good for LeBlanc when she can weave in and poke, but its value depends on positioning.²¹ 8x2 duos
• LeBlanc can gain stacks by last-hitting champion clones, including her own clones.²² 8x2 duos
