Blade

Blade is a mobile meleecarry with a lot of singletarget damage, two ministuns (one of them bounces)  and a charge. Once in position, his target gets nuked.

Oh, did I mention he's able to stealth and cleanse?

Some of his attacks are stronger if they're executed from behind. Once you've reached that carry's back, he very rarely escapes. A speedboost, Blade's stuns and slow and the charge make it pretty difficult to flee from his claws ehh blades.
