Mana Ryze
I belive this is the path to
's fighter potential. He can get some really spammy spells to quickly get his shield which scales off his Mana, that mixed with some AD allows him to (Theoretically) become deceptively durable and an effective duelist.
Feel free to comment how you would build him, and (If you did play him) how you feel about the idea in general, like it if you like the idea, and leave peacefully if you don't (No down vote, no comment unless you have actually tried the idea)
