Champion Idea: Waluigi

Hey everyone! I decided that i just don't care anymore so I decided to do this with my friend (his IGN is DerpyBrian). Nowhere near anything complete, and most numbers are not included unless we thought they were necessary. Waluigi is meant to be a ganking jungler/top laner who has a big impact on teamfights due to his ability to produce large amounts of cc while also being highly mobile. Anyway, here it is:

Passive: Wah Every basic attack, Waluigi gains a Wah stack, up to a cap of 10 stacks. When he hits an enemy champion with a basic attack, all Wah stacks are consumed, dealing a small amount of bonus attack damage based on the number of stacks.

If Waluigi has at least 5 Wah stacks, he hits the enemy champion with a tennis racket, dealing magic damage. If he has 10 stacks, he supercharges his racket and deals twice the magic damage.

If Waluigi gets an assist, he instantly gains 10 Wah stacks.

Q: Assist Trophe For Waluigi's next basic attack, he deals [amount] bonus damage. This auto attack gives Waluigi one extra Wah stack and applies brittle for 2 seconds. Assist trophe cannot apply brittle to the same champion for 18/16/14/12/10 seconds.

W: Trophe Sweep Waluigi swings his assist trophe in a cone, dealing [amount] damage to all enemies in the area. For every enemy hit, Waluigi gains a Wah stack. After adding these, all Wah stacks are consumed, dealing bonus magic damage to all enemies hit, increasing based on the number of stacks.

Every time Waluigi gains a Wah stack, Trophe Sweep's cooldown is decreased by [small amount].

E: Double Dash Waluigi dashes in a target direction, and for a few seconds, Waluigi can recast the ability. The closer the angle is to the original, the dash becomes shorter, up to half of the first cast. The further the angle is from the original, the dash becomes longer, up to 1.5 times the first cast.

If Waluigi hits an enemy champion, he slows them for 50%. If the champion already has impaired movement, Double Dash will stun them instead. (Multiple champions can be affected by this ability.)

R: WAAAAAAH Waluigi captures a smash ball, giving him 10 permanent Wah stacks, increased attack damage and movement speed, and 10% cooldown reduction for the duration of the ability.

Well, that's it! To be completely honest, I really like these abilities (especially his e), and would love to see them on an actual champion. I'd love to see anything anyone has to say either to improve the kit or to just tell me to get a life. Once again, thanks to my friend DerpyBrian who co-created this with me!
