Turn 1: Land, bird.
Turn 2: Land, Tap out, Geist and Rancor, swing 4.
Turn 3: Land, lay a Borderland Ranger swing another 4.
-This is where they Slagstorm or something-
Oh wait, your geist comes back along with Rancor? Sweet. The Borderland Ranger died, but we got our land from it. Birds did it's job.
Pretty much try to keep aggressive with out playing your more valuable creautres. Prefferably play you're more undying, less valuable creatures early game while still keeping the aggro up then play your more big hitters when he runs out of fuel. If he manages to land a titan try to swing into it then Dismember/burn it for the kill.
Again, I haven't ran into many wolfrun decks so following my advice wouldn't be best.
But what I can tell you is how to sideboard or how I would sideboard.
+2 Beast Within
+2 Zealous Conscripts
If you manage to land a turn 3-4 Manabarbs while having 5 or more life than your opponent, you'll most likely win.
