LeBlanc - Mechanic idea
Smoke and mirrors. Basically it's Distortion but...
LeBlanc dashes to a target point. At the place of her origin a clone appears. Clone mimics LeBlanc movement (only movement). She can recast ability to seamlessly swap places with clone.
Clone shows the same stats but disappears after taking damage. If LeBlanc attacks or casts another ability - clone doesn't mimic it. Clone doesn't clip through walls so it's another way to tell this isn't LeBlanc.
What this achieves: -deceiving thematic (with mirroring and seamless swapping) -assassin exit tool -outplay possibility for enemy (distance between clone and LB in normal situation is preserved, comparing to current Distortion which allows to cover big distance and blink back)
Downsides: -pushing clone into wall can look weird -it somewhat copies Zed's shadow swapping
