Who's a great lane duo with Rhasta - Shadow Shaman? ;)

So my bro and I want to lane together for once, (we always play and somehow manage to NEVER lane together...which is FUN) He plays a sick Rhasta and so I want to pick something to practice the shit out of so we can have a nice duo going!

For whatever reason we were talking about it at 3:00am one night and we concluded that Witch Doctor would be amazing coupled with Rhasta. After numerous attempts we discovered that is not the case. So DotA2 redditors what IS? ;)
