Pokemon Re-Designed as League Champs

I've had this thought for a while, but what if Pokemon were legit League champs? I'm not talking like "Oh, Kennen is Pikachu" either. I'm talking, a full transfer of concept into functional League character. I mean, the abilities have a similar structure. A passive and four abilities or in Pokemon it's an ability and four moves. Moves can only be used a limited amount of times based on a resource. Mana in League, Power Points (PP) in Pokemon. So, I figure, to pass the time or just get the ideas onto paper. I kinda wanna try coming up with thematic and unique sets using either the more popular Pokemon if not the entire roster of 721 Pokemon (Though I won't bore anyone with all 721 Pre-Sun&Moon Pokemon). And to christen this potential series, why not start off with Pokemon's, "Oh (Not) so lovable," mascot, Pikachu.

Pikachu - The Mouse Pokemon

Passive - Static - Pikachu's damaging abilities and basic attacks apply stacks of Static. Each stack of Static slows the target slightly for a short time, stacking up to five times. When Static is fully stacked, the stacks are consumed and the target is stunned briefly. This effect cannot be re-applied for a short time after that. Stacks last for a short amount of time after they're applied.

Q - Electro Ball - Pikachu fires a short range projectile that stops at, and damages the first enemy it comes into contact with. Electro Ball scales with AP, doing bonus damage based on the difference in Movement Speed between Pikachu and Electro Ball's target. Electro Ball applies one stack of Static.

W - Agility - Pikachu passively gains a small Movement Speed bonus. Activating Agility grants a large bonus to Movement Speed for a brief time.

E - Thunder Wave - Pikachu fires a wave electricity in a cone in front of it slowing enemies and dealing meager damage scaling with AP but applying two stacks to every target hit.

R - Thunder - Pikachu calls a storm down to strike every marked target in a large area. Thunder deals a large amount of damage scaling with AP.

Recommended Summoner abilities: Ghost and Heal/ Ignite/ Teleport

Ghost because it synergizes well with Electro Ball

and...

Heal because staying stocked on potions is always good/ Ignite because type coverage is good/ Teleport because Pikachu is a Season 6 LCS wannabe going for that TP meta (Or was that Season 5? I've already forgotten)
