Use Bramble Maze to contest the first rune. You are extremely fragile, use Shadow Realm to avoid being hit and strike back from afar. Cursed Crown stuns but has a long delay, too long to be of use in the lanign stage. Use Bedlam on your strongest melee hero (don't pick Willow if you don't have one) and get them to go in, use Terrorize to effectively stun foes (don't use it to escape unless you absolutely have to). Only buy Spirit Vessel if the enemy team has a Huskar, Alchemist, Pudge or Pugna. Otherwise buy Solar Crest.
