Turn A Pokemon's Moveset into a League Champion

While looking through Pokemon for a team I realized that some Pokemon could make a transition into league with potential movesets as a Pokemon has an ability and 4 moves same to league's passive and 4 ability's. So how would this work well I am going to list a Pokemon and a potential moveset it can have and try to move said moveset into League. Here would be an example.

Aegislash: Ability: Stance Change, Moves: Sacred Sword, Shadow Sneak, King's Shield, Sword's Dance.

Now we would make up a moveset for a champion with the moveset used above.

Passive: Using a offensive ability switches the champion into an offensive stance boosting Ad and atk speed but lowering Armor and Magic Resist. Using a defensive ability switches the champion into a defensive stance boosting armor and magic resist but lowering ad and atk speed.

Ability1: Slashes a small area in front of the champion dealing damage and lowering the armor of champions hit for a few seconds.

Ability2: The champion can hold the button and the longer the button is hold the farther of a distance the champion can blink to but is slowed while charging it, like vi's vault breaker, and yes I got this idea from Greninja's Shadow Sneak in SSB4.

Ability3: The Champion ready's his guard allowing him to block Attack Damage similar to a Morgana black shield with Magic Damage but does not negate cc instead while the shield is active any champion that hit's him with a move that does Attack Damage or an Auto will have their ad lowered for a few seconds. This does not block magic damage btw.

Ultimate: The Champion Bide's his time holding his ground and suppresing himself, after a few seconds, if it is not stopped with cc the champion ready's himself doubling his Ad for a small time.

That would be a moveset I would give for Aegislash if he was in league but this is not a perfect set up and their can be multiple ways to represent one Pokemon, I was thinking of giving him Iron Head instead of Sacred Sword but not sure what cc I would apply for a flinch. If you would like to post what Pokemon moveset you would like to see in league post them in the comments and feel free to make up how a Pokemon move could work in league like what I did with Shadow Sneak although I did grab it from smash.
