Create-a-champion

If you could create a champion, compiled from abilities and attack methods of already existing champions...

(PLEASE explain what each ability does at least with some detail, or else, it's impossible to read some of these.) Mine: Meele champion Evelynn's shadow walk passive (Stealth and 1% mana regeneration occur after 5 seconds out of combat) Lee Sin Q Sonic Wave/Resonating Strike (Lee Sin's sonic wave is a skillshot, if it hits a target it provides visibility, does physical damage. If Q is activated again within two seconds of hitting a target, you fly towards the target (through walls), and then deal 8% of the enemy's remaining health)

Gangplank W Remove Scurvy Gankplank's W heals him, and removes all forms of CC. (80-360 HP, +100% AP) (22-18 second cooldown)

Soraka E Equinox Soraka's Equinox, for 1.5 seconds creates a silence, and applies initial magic damage (+40% AP). After the zone closes, all champions are rooted for 1-2 seconds and take approximately double the magic damage, not including AP stats (+80% AP).

Leonidas paradrop R Leonidas jumps out of a C130 and performs a high-altitude-low-opening paradrop, maiming everything in the impact zone.

Try to create something more OP.

Personally, this is just about the most versatile assassin you can have. The best passive in the game, with a flash gank ability, HP regen and anti-CC. And a silence and AP AOE attack. Basically... Either open with an R, silence with the E and kill all escapees with Q. Or just open with Q, E and win.
