Illusionist Support
I know Leblanc fills the whole Illusionist character, but this idea is more for fun than an actual idea for the game
Passive - Artificial Army - Creep Waves that pass by you gain 3, 1 health fake minions that grant no gold, they do however pull minion agro and tower aggro before other minions, and look like full health minions to enemy players Along with this, all of your (ranged) autoattacks gain 5% AP scaling and 10 range for every illusion that you currently have produced.
Q - Fake Pink Ward - Just at the name sounds, you may place up to 3 fake pink wards, these do not give vision or gold when destroyed. However when they are destroyed you receive an indicator that they were destroyed.
W - Illusory Vision - Place a ward that lasts 15 seconds and looks like a normal ward to the enemy, and looks like it gives vision, however this vision is fake and only shows neutral monsters not doing anything, and doesn't reveal your allies. This does not overwrite actual enemy wards. You can have up to 2 charges of this. Enemies within the range of the ward are slowed by 10%, this stacks with multiple wards.
E - Non-Wounded - Cast on an ally to make it so their health appears to be at a quarter of what it really is to the enemy for a few seconds.
R - Trick Clone - Create copies of your entire team at where you cast, they do no damage and take damage twice as fast, they also do not pull and tower aggro or minion aggro.
