Pretty simple strategy here. Twisted Farmer, Foraging Tri-Toe and Rat King are all able to create sacrificial tokens, which in turn pump up the stats on Direwood Pack. Glen Pathcutter also makes good Pack fodder that we can play early in the game to slow down aggro decks if necessary. The Uncountable also does a good job preventing the AI from attacking, and we can use it to turn our tokens into Impending Dooms later in the game. Use Vengeful Flight to duplicate Pack, or bring it back from the void with Sinister Rumors if it gets killed. The rest of the deck mainly serves functions as removal and extra card draw. Feeding Time and Maveloft Huntress are obvious includes, but you may want to switch out Thicket Trap or Toxicology to other cards if you prefer.
If you try this deck in Gauntlet (or Throne) and have any suggestions for changes, please leave a comment. Thanks.
