Breakneck Rider  ^Flip is a better 3 drop when it flips than Shrill Howler  ^Flip

It's more about the 3/2 eldrazi tokens

Charman456,
A few thoughts ...

• In a world with UW Flash and Smuggler's Copter, I'm not sure you can keep Arlinn Kord  ^Flip alive long enough to do any good, unless you mainboard a bunch of Flyerhate or your own Copters
• Speaking of which, Wolves are notoriously weak to Flyers, so no matter you you do about Arlinn, you'll probably want some Flyerhate in the sideboard (or maybe even the mainboard, depending on your meta). I like Clip Wings for Emrakul and Indestructible flyers, and some combo of Weaver of Lightning, Vines of the Recluse/Aim High, and Tears of Valakut for everything else. Lots of people seem to like Take Down, but I'm not a fan at all, since it can't hit Smuggler's Copter.
• Blossoming Defense might be really good in here. I like it in sideboard, but if there's a lot of Burn and Control in your meta it might even be worth mainboarding.
• You might also want Natural State or Appetite for the Unnatural in the sideboard, for Authority of the Consuls, Fevered Visions and all the Artifacts from Kaladesh.
• I ran Cinder Glade as a four-of for a while, but found the upside (better fixing) was not worth the downside (entering tapped more often than I wanted). May be worth testing with fewer, if you haven't already. I found the sweet spot for my deck as a two-of.
• With all your Flip wolves, I recommend a full set of Neglected Heirloom  ^Flip.

Draw well!

clayperce makes some good points.

sweet deck, check out my standard deck with a similar strategy http://tappedout.net/mtg-decks/mathsheep-is-fun-etc/ if you dont mind im trying to break 100 upvotes. every single one counts!

Charman456,
I'm not sure about Natural State since it can't hit Aetherworks Marvel. You might consider Appetite for the Unnatural, Natural Obsolescence, or Release the Gremlins instead.

I'd be intrigued to know how this build performs.

I'd consider including something like Shock that doubles up as target removal and hitting in for those last two points of damage after a heavy strike.

Additionally Vines of the Recluse is a variant of Aim High that has the advantage of a lower mana cost.

There's also Spidery Grasp that has a similar function.

And Synchronized Strike as well!
