What do you suggest as replacement for Collected Company?

I'm thinking about duplicating this deck after game-day and I don't have CoCo or Atarka's Command.

Arlinn Kord  ^Flip. If you are on budget, go to Evolutionary Leap this enchant is wonderful as it counters opposite removal spells. And Lambholt Pacifist  ^Flip

snarlmkiv if you want a direct replacement, I would suggest Pack Guardian. At best you're guaranteed a 4/3 body (which is bigger than any human werewolf) and a 2/2 if you have an extra land, at worst you're able to flash in a decent blocker without the 2/2 :(

Arlinn Kord  ^Flip is good, but you would need to change the deck around a bit and adopt a more midrange strategy. She honestly just doesn't do it for me.

I share the same sentiments as you with Arlinn Kord  ^Flip. She's hit or miss for me and she doesn't really guarantee complete win-con if your board is close to 0...

Also I modified my deck to work around building a stronger board presence minus Zada and Silverfur because they're so easy to side against. Gruul Werewolves with Removal - Budget.

Remove Zada and your deck is good as deck. That's why I'm going for the more Aggro approach.
