I would probably move the Duskwatch Recruiter  ^Flip or stuffy dolls in some quantity to the sideboard because they are so mana hungry for the Geier Reach Bandit  ^Flip

Looks awesome dude. Only thing I can think of is maybe a Beast Within in the sideboard since you'd be killed pretty easily by combo decks and stuff like that in Modern. +1'd

AEther Vial is wicked when it comes down to werewolves, then you have your mana available for abilities(Cough duskwatch cough) and instants. With vial they can transform the same turn they come in, and you pressure you opponents to cast stuff even if they don't need it. So you get rid off things like path to exile sooner. You can try Dismember too.

Thanks for both of your suggestions. So, I added a Beast Within in the sideboard. I also highly consider Dismember, it will stay in the maybeboard until i found what to cut. The AEther Vial case is more complicated, i actually own none of them and are quite pricey at the moment, i have more important deck to invest in before this one, but i would make the deck a lot better.

Another good removal, if you are not a big fan of Dismembering things, is Moonlight Hunt, it is surprisingly good with this tribal deck, specially when I see you like to have tokens, it's probably the best creature removal you can have, werewolves die a lot to fliers (Inkmoth Nexus, Lingering Souls, etc etc) Another good sideboard piece is Witchstalker (the hexproof comes in very handy against removal). one or two copies of Raging Ravine can help you survive after a board wipe as well.

I wasn't aware of Moonlight Hunt, unfortunatly, its can't target our own Stuffy Doll, that could have been nuts. There's already a Raging Ravine in the deck. Witchstalker used to be in the sideboard actually, ill think about its comeback. Your suggestions were helpful once again, but i don't want to make many change to this deck until Eldritch moon and its potential new werewolves and wolves will be spoiled. But im pretty sure Dismember will make the cut until then.

I would play the full four of Howlpack Resurgence. It's the best thing Werewolves have gotten from SOI block. Also four Moonmist because instant speed transform wins games.

I planned to make the list more consistent by playing playset of the cards that proved to be the most effective. Do you suggest any cut?

Either Geier Reach Bandit  ^Flip or Collective Defiance for the resurgence. They clash in your 3 drop slot with Immerwolf and Spirit of the Hunt, which isn't good for your curve. I'd cut Rancor for Moonmist, as the buff the mist grants you outweighs the buff from rancor. I could be wrong but that's what immediately comes to mind.

Thanks for your insight, i will cut Collective Defiance for Howlpack Resurgence since the former isn't an instant. Ill cut the two Rancor for the fourth howlpack and for another Moonmist. Ill try with that list for now. Thanks a lot for your help.

Anytime. I'm not the best player ever, but I'm happy to help. Good luck!
