Don't be overaggressive, don't sell your big items but buy a Reflex Block to block his stun and maybe some armor (not recommended) if absolutely necessary. The biggest mistake that most people make is that people forget that Koshka is an assassin, not a melee warrior/brute. You should get in, do a bunch of damage to their laner carry with your allies, and get out and wait for your abilities to cooldown again so you can go and finish off the laner(if he's not already dead). Also, always stick...
