Yo guys my name is doki000 EUNA and i'm about to introduce you a new roll that i made out. So concept of this roll is just go around the lanes and supply them with mana and health. I've presonaly tested it a lot of times and it works incredibly well. So new META is:
-1 Jungler
-1 top
-1 mid
-1 bot (adc going more tanky)
-1 supplier (you)

You wanna stick with beginner supp item Relic Shield, to give laners health and gold but still you getting some gold and experience, you have right to tax since you heal them and give them mana (Trade). Then you just stick with the basic items such as Sightstone for map awarness and you can even buy Vision Ward that last forever.

You definitely wanna get Mobility Boots for, well mobility :D. So you can fly around the map and supply, this roll is kinda like supp but a lot more fun to me (a lot more). Now once you bought that you pretty much stick with the power up items such as Banner of Command, Ohmwrecker,, Twin Shadows and stuff, make sure you buy rabadon's death cap for more AP.

Take Teleport and Ghost for mobility around the map! you can take some other spell is you think it would be better but Teleport and Ghost work best cuz you aren't really so mana depended to take Heal or Clarity.

Make sure you take E on first level to give you mage mana, and then take heal, build heal and mana giving at the same time so you can supply your allies a lot better.

Just make sure you have ap runes it doesnt have to be this ones.

Pros: -global map sustain + your ult
-Lanes can be agressive
-Better map awarness
-Better early game (early wins)
-Quick help (you are everywhere)

Cons: - 1 person on bot vs 2

Its important that on beginning you stay wit your mage to give him mana adventage and to be agressive, later on you just supply other lanes or the jungler. an make sure you tank the damage so your allies can do the dmg.

Hope you enjoyed it and gl and hf.
