(Champion Concept) Yin & Yang

Heres an idea i came up with for a champion, not done yet but i figured you guys could help

Name: Yin & Yang basically 2 yordles with different abilities (i know they had a concept before for a 2 yordle champ)

yordle support Melee Auto Attack(like a kung fu)

passive: Increase mana regen in yin form, health regen in yang form yin

q - heal % based on something w - slow the atk speed of target and damage e - passive (inner peace) increase the mana regen of people within a certain range r - switch to yang (like a 30 second cd)

yang q - % damage target based on something w - increase atk speed of target e- passive increase the health regen of champions within a certain range r - switch to yin (30 second cd)
