New demacian army - MIKE , the Medic of Demacia

I were thinking about a new champ for demacia that can play supp, cus I think that we don't ( maybe ) have demacia supp. So I made 1.

Story:

Mike are smart and brave, he maybe not strong bot he can think some way to defeat his enemies. One day after he finally became 1 of the demacia army, he go back to his home to tell his mother about the good news, suddenly, her mother been found with blood on her body, Mike shocked and cried. Then, Garen came to Mike and tell him that never give up. That's make Mike feel okay a little bit. So, Mike start to investigate who murdered her mother. Mike found a trail, and the trail looks like wolf feet. Now, Mike learn more medicine and techniques so he can hunt down who murdered his mother.

Never give up, Never surrender - Mike

*Well I am bad at English xD

Passive - borrow

Mike can borrow any Allie basic atk as his basic atk, if he out from the range, he will return back the item he borrow. ( He is melee ) n the range radius is like ward vision radius.

Q - 1st Aid

Mike will + 50% of his or Allie current HP

W - Last Stand

Passive - Mike grant movement speed if his HP is under 30%

Active - Mike will shot 6 bullet. Each bullet give 6% of life steal on hit. If all bullet hit, he will grant health and mana regeneration for 5 sec

E - Injection

Mike will choose 3 type of injection ( like twisted fate choose his card ) and use it for him and his Allie in the area

Type:

1. Health
2. Atk Dmg
3. Shields

R - Help

Mike will be able to target low Allie health or dead Allie/enemies body as shield ( you know it's like people lift people on his side like that ) (only 1 champ ) then, he can use all of the abilities according to who his holding ( all of Mike skill are disabled ) ( and the champ ability that he help are refreshed ) ( and the CD of the abilities that he use according to the current champ CD abilities ) - after the duration end, if it is an allie, it will be on a full HP, if it is enemies, - it will revive at a half of HP

Whut do you guys think about my idea :D
