You know how at the start of some games you can ban a hero? Here's a tip. Ban Venomancer. Because if you don't, things could get real annoying.
A trick has been discovered in the latest version of the game that allows Venomancer to effectively stack 5 of the neutral camps at the first level, if you're on the Radiant side of the map.
It's not mechanically easy, but skilled players should be able to pull it off. And it's also a super effective trick if you're in a team — the Venomancer can stack the neutral creeps for another hero (like Anti-Mage or Legion Commander).
You can use the same trick on the Dire side of the map, but you'll only be able to stack 3 of the neutral camps. It's useful if you're playing a dedicated support, although you do have to deal with the small downside of playing as Venomancer, and a support Venomancer at that.
Still, it's a handy tool if you're the generous type and want to help one of your carries get off to a great start.
