Very accurate to the actual character (gotta love Skullgirls :D), but a lot of the mechanichs would not work very well for LoL (especially the Defibrillator thing). The scalings are also very off (to high: %hp on Passive, AP scaling on DPS at purpule vial, EKG flatliner, Damage per Scalpel), check similiar abillities for better balance.

Also, random vial isn't very good, I would suggest first use: orange, second use: green, third use: purple and repeat. This allow you to set up your own tactic smarter. The green vial would also be more accurate, useful and understandable if it was "will stun the enemy for 1 second next time Valentine inflicts physical damage on the target", giving a nice combo with "savage bypass" and "checkmate incision". And by input lag on the orange I assume you mean Atk-speed slow (and possibly a movement-speed slow too)

"Savage bypass" is fine, but "EKG flatliner" don't make much sense to me, I sugget you just use one of them and balance it.

Checkmate Incision has a strange mechanic in general (also, the stun part is not needed if you apply my version on the green vial), maybe a bit fewer scalpels and work a bit like graves "buckshot" but all projectiles flying parallell would be better.

And lastly the ult, reviving in LoL is very sceptical in general (also, physical damage?), applying stun on all enemies hit or a buff on (living) allies in range would be better.
