Su'Marek

First off, I'll let Riot do their thing with stats. but this guy is half attack and half magic for ability scaling.

Passive - Tidal Surge The more abilities used, the faster he moves and attacks. stacks up to 3 times and 5% movement speed bonus increase and attack speed increase

Q ability - Tsunami Su'Marek will gather any allied champions with him and surge forwards into a dragon shaped wave. dealing damage on first enemy champion hit. the more allies, the more damage. 50/50 on physical and magical scaling

W ability - Spout Su'Marek will call forth a spout of water from the ground. knocking up enemies and disrupting any channels. deals half damage as magic on knock up, and the rest as physical when landing. 2/3 magic scaling, 1/3 physical scaling.

E ability - Mistify Su'Marek turns himself into a mist, unable to be harmed or targeted. he has 2 seconds to choose an enemy champion to reform around in a root and deal three attacks. the first two are magic infused claw attacks, the last is a huge chomp from his jaws, dealing 10% of current heal as bonus damage. each attack can apply on hit effects. 2/3 physical scaling, 1/3 magic scaling.

R ability - Perfect Storm Su'Marek catches the victim of Spout in mid air and summons a small hurricane. Su'Marek gains power from spinning around in the hurricane to slam his target down and enhancing the second half of Spout's attack. causing an aoe of damage and slowing targets around by 15%. Executes target if below a certain threshold. 50/50 scaling between magic and physical

any constructive feedback would be nice
