Gameplay tips from sbergs:

Few tips on playing: The hardest part of OTKing is getting Snowfall Graveyard, so you mulligan hard for that, along with Gnolls and tradeables. If you get Finley, play it turn 1 unless your hand is amazing.

Otherwise you generally use your tradeables until about turn 3, then open with either a Gnoll or a draw card like Shroud or Passage and try and hit Gnoll. Use your Gnolls to survive the early game or get chip damage in, and then kill with the Snowfall/Mine combo.

The quick math on the combo - If both Necrium Blade hits go face, that's 6 damage. Necrium Blade proc on Mine (w/ Snowfall) is 16. Naval Mine DR (w Backstab) is 8 damage. 6 + 16 + 8 = 30. The Forsaken is an extra 8, or Sketchy can pull Mine/Blade from the deck for more damage.
