If you get the Broomstick Witch to fly over to an enemy site away from defenders, you can Recall all of your wolves there at once and alpha strike for insane damage. Then you can spread out to finish the game.

I could be talked into using the Sorcerer just because it's a great choice, but I think not having to worry about threshold open you up to a much wider range of available spells and I could splash anything else as needed.
