LeBlanc, the Deceiver is a champion in League of Legends. I make a small rework for her cause of her recently silence removal. Anyway, before that, I started to make a Mirror Mage (she used to be a tank but then I moved it to a mage, which become ... LeBlanc) so why not make a small rework.
Whenever LeBlanc is below 40% health, she creates a controllable clone of herself for 10 seconds with 53 + (17 × LeBlanc's level) less health. She and her clone become stealthed for 1 second. If the clone died during 10s duration, the cooldown is halved.

Active: LeBlanc projects an orb towards her target, dealing magic damage and marking the target for 3.5 seconds.
If the target takes damage from one of LeBlanc's abilities, the mark is consumed, dealing bonus magic damage.
If the target casts a spell, the mark is consumed to negate the spell. The spell then can be used with Mimic.
Active: LeBlanc flings illusionary chains in a line, dealing magic damage. The chains then leashing for 1.5 seconds to the last enemy unit it hits. While the leash persists, the target can't not use dash/blink spell.
If LeBlanc remains within 1000-range of the target for the full duration, the target takes additional magic damage and is rooted for 1.5 seconds.
