A Mono Green Tribal Wolf Deck
12 wolves for 1 mana can be quite nice with the lord effects, undying and mana sink abilities can be very helpful in some games
Packsong Pup usually starts attacking as a 3/3 for 2 at least that keeps growing if not removed and if killed nets you life
Silverfur Partisan discorages opponents from trying to interact with your wolves with spells. Works quite nicelly with Setessan Tactics as combat trick and making a 2/2 wolf token for each target and allowing to block and fight if needed.
Wolfir Avenger is one of the flash wolves and it's regenerate ability can be quite relevant
Nightpack Ambusher gives +1/+1 bonus to all your wolves, generates 3/3 tokens is a 4/4 for 4 and have flash, it's quite great.
Howlpack Resurgence really help giving trample and having flash allows Nighpack Ambusher to still generate the token of the turn and flash a +1/+1 bonus in opponent's turn
Sylvan Anthem is another lord effect for 2 that helps you filter the top cards for what you might be needing.
Gingerbread Cabin can provide some life and taps for green
sideboard is a bit generic.
Cemetery Prowler can help against some decks that uses graveyard, reduces the cost of your spells.
Wicked Wolf is nice to bite off some pesky creatures
As far as I tested Ascendant Packleader it hardly ever got even a counter so I was testing with Snarling Wolf which was usually better in it's place as I could at least turn it into a 3/3 growing past the 1 toughness even if temporarily when the +1/+1 effects were not out. Werewolf Pack Leader and Mayor of Avabruck
can be good additions to the list in that slot though, Pack Leader being a 3/3 for two and drawing cards can be amazing and Mayor can lead to a easy win if not interacted with but can be slightly tricky at times, maybe with Vivien, Champion of the Wilds to provide flash could help with it and Nightpack Ambusher too.
