So basically. You make a champion using parts of a champion.
My champion would be this.
Urgot.
Passive: Taric's Gemcraft
Q: Xin Zhaos Three Talon Strike.
W: Zileans Rewind
E: Trundles Pillar. Because TROLOOLLOL.
R: Karthus Requiem
Why is this kit OP? He is ranged and he can requiem every 10 seconds. Plus he's urgod.
We have Bronzodia tho.
Azir
Passive: Warpath
Q: Powerball
W: Sadism
E: Devasting Charge
R: Thrill of the hunt
Why? A giant chicken running around that will one shot you with an aa and that can be invis
Teemo
Passive: Arcane Mastery
Q: Rewind
W: Dazzle
E: Decisive Strike
R: Final Spark
Why?, Because everyone will have a real reason to hate Teemo XD... At least more than now (Cue evil laugh)
Master Yi
Passive: Voracity
Q: Siphoning Strike
W: Remove Scurvy
E: Sadism
R: Destiny
Why? To give the current Master Yi haters something to REALLY complain about. He teleports to his target, wipes them out with insane damage and practically resets all of his cooldowns by killing them. Then he repeats.
Oooh! let me try!

Rend
and top it off with just a hint of 
's Whirling Death.
