New Mid Champion Concept

Hi. I was thinking of a new mid champion concept and I hope that Riot would see this and think about my ideas.

Passive: Gulf of Mana - Everytime you use a skill 5 times under in 30 seconds, you pour out a sea of mana which when ally champion including yourself goes in, you regenerate mana fast.

Q: Mana Sword - The champion makes a sword out of mana for 5 seconds and the champion's damage is increased by 1.5x/2x/2.5x/3x/3.5x Mana cost - 40

W: Orb of Mana - The champion makes an orb made out of mana which attacks the champion by 30/60/90/120/150 + AP Mana cost - 80

E: Blast Off - The champion makes a mana bomb on the floor and detonate it. It makes all champions inside the circle fly off and deals a damage of 20/30/40/50/70 + AP Mana cost - 120

R: Begone - The champion slashes the enemy champion many times that you are not able to see on the screen. It deals a damage of 120/150/180 + AP Mana cost - 200

I hope you like these ideas and please comment down below. Thanks for reading :D
