Yet Another Champion Idea

So I changed up my last champ idea a bit, this champ is going to have two of the same abilities from my last idea, but with a couple slight changes. I hope you enjoy the idea of this champion. I have included a picture for the abilities once again.

Auto attack range is similar to Thresh or Rakan

Passive,

Whenever you kill someone who killed you last time you died, you gain extra gold (idk how much would be balanced)

Each time you take damage from an enemy champion, you gain one stack of revenge.

Revenge: After getting damaged by an enemy champion, you gain one stack of this. When damaging enemy units, it consumes one stack of revenge, deals bonus physical damage and heals if the stack was consumed by an auto attack. (maximum 5 stacks) (If next attack consumes revenge and gains a stack, then the number of stacks remains unchanged)

Anger: Enemies with this take extra magic damage from your attacks (Max stack of 1)

Q,

Standard skillshot, shoots wind magic in a straight line. It goes through units. Each unit it goes through, the skillshot does less damage, but if it kills a unit, it keeps its previous damage. Every # amount of units it increases damage and speeds up until it hits half of its range. Once it hits that point it starts to decrease damage, but maintains its speed. Slows every target hit. (Range would be similar to Nidalee Q, width would be similar to Ezreal W, but perhaps a slightly smaller width). Enemy champions hit by this gain a stack of anger.

W,

Throws flail forward, planting it in the ground 300 units in front of her, doing aoe damage around it and a cone of damage in front of the aoe circle (The cone slows and the circle stuns for .5 seconds). Recast anywhere around the ball of the flail in order to fling herself to that location (maximum range of 300 units, if she flings herself towards someone with a stack of anger, she gets a bonus 150 units of range)

E,

For 5 seconds, break the cap on revenge. after the 5 seconds, keep stacks earned and don't gain any more until stacks lower below 5. Next auto attack applies anger to the enemy hit.

R,

Consumes all revenge stacks in order to swing her flail in a huge cone in front of her to knock enemies to the outer perimeter of her R range. Slows enemies hit for 1.5 seconds by 50%. (More stacks=more dmg). If an enemy dies within 5 seconds of taking damage from this ability, gain max stacks (If already at 5 stacks or higher, don't gain any more). If an enemy with anger is hit by this, consume it for bonus damage and reapply it.
