Jinshao, the Keeper of Balance
Jinshao is a melee bruiser that can dish out a good amount of damage while also becoming stronger the lower in health he is.
Passive: Strength in Weakness- Jinshao gains bonus attack damage equal to 5% of his missing health.
Q: Gloomerang- Jinshao tosses out his weapon that flies out quickly, dealing 10/40/70/100/130(+40% AD) physical damage to enemies it hits. After a 1 second delay, it flies back quickly, dealing 15/60/105/150/195(+60% AD) physical damage to enemies on the return. Jinshao gains 6% move speed for 3 seconds for each enemy hit. Cost: 40/50/60/70/80 mana Cooldown: 11/10/9/8/7 seconds Range: 825
W: 3 Sided Strikes- Passively, Jinshao's auto attacks and abilities add a stack of 3 Sided Strikes to the enemy for 5 seconds, stacking infinitely. When activated, Jinshao rips the stacks from all enemies affected, dealing 3/6/9/12/15(+3% AD) physical damage per stack. For every 3 stacks the target has, the damage is increased by 33%(for example, if they have 15 stacks, with this at max rank, it would deal 936(+187% AD) physical damage). Cost: 10% of Jinshao's current health Cooldown: 32/29/26/23/20 seconds Range: 1200
E: Vorpality- Jinshao causes himself and an enemy to teleport in the middle of where they were. Jinshao appears behind the enemy and deals physical damage equal to 6/7/8/9/10% of the target's maximum health. Cost: 60/65/70/75/80 mana Cooldown: 18/16/14/12/10 seconds Range: 625
Ultimate: Triangular Death- Jinshao creates a triangular zone on the ground for 3.25 seconds, slowing enemies inside by 25/30/35%. After the 3 seconds, the zone erupts, dealing 400/700/1000(+300% AD) physical damage to enemies in the middle, down to 30% damage at the edges for a minimum of 120/210/300(+90% AD) physical damage. Enemies hit are also slowed by 80% that decays over 1.5 seconds. Cost: 100/125/150 mana Cooldown: 120/100/80 seconds Range/Height/Width: 700/900/800

Counters to Jinshao:
Kalista can keep her distance and kite away from Jinshao before he can really do anything. He only has 1 gapcloser and his only cc is a slow on his ult, so Kalista should be able to slip away from him with ease.
Same thing with Kalista, Ahri is too mobile for Jinshao and can easily catch him or get away from him.
This can go with pretty much any assassin, because they are able to quickly burst Jinshao down before he can stack up his W or get his ult off.
Champions Jinshao Counters:
Jinshao pretty much counters every duelist. He can stack up his W in long fights and get his ult off.
Jinx is squishy and immobile, and Jinshao can easily dodge her chompers with his E.
If positioned correctly, Jinshao can use his E to get Fiddle away from his team, and when he uses Zhonyas Jinshao can drop his ult right on top of him.
