Lyndon by Porco

Lyndon is an ambusher with many interactions with bushes : his Q doesn't reveal him if shot from a bush (but a little animation can give a cue about his location). His trait allow him to teleport from and to a bush, and his smoke grenade can create a bush everywhere.
Dirty fighting gives him some defence by isolating an enemy hero.
His cluster arrow ult is a "all in" : great damages and no cooldown but a big mana cost that can leave him without defence.
The other ult, sentry, gives him a good zoning and ambush power, by copying his Q spell.
Thanks to his design, lyndon works good with dehaka.
