Unlike many other champions, LeBlanc can deal Magic Damage to any of the targets in an AoE. She can also take on the appearance of other people, and clone them. She has a high skill ceiling, but this makes her hard to play.
The best way to play LeBlanc is to use a strong gank setup. This can include using a W-Q combo or a W>R combo. This combination is effective in closing on an opponent, and can be used in a teamfight as well.
The other way to play LeBlanc is to build a burst-damage setup. This means you'll focus on items that will help you maximize the AP brust damage.
LeBlanc's ultimate, Mimic (R), is a very powerful tool. It enables LeBlanc to recast any ability. This makes it versatile and a good tool to use in a variety of situations.
In addition, LeBlanc has two gap closers. The first is the Ethereal Chains, which is a skill shot that forms a tether between LeBlanc and an enemy. The other is the Mirror Image, which is a single-target spell that can be controlled by an Alt key.
This makes LeBlanc ideal for solo killing opponents, and allows her to one-shot creep waves. She can also snowball lane with ease. However, she is generally avoided if she approaches the front of the team fight. Fortunately, she has a number of tools to avoid ganks, such as her ability to manipulate the crowd.
