Mono Shadow deck focused on minotaurs and weapons.
Works surprisingly well in the current format. Now that it has been reduced to 2 cost, Collection Rounds is a pretty good card to play fast on the enemy's turn at the start of the game, and helps stabilize against aggro staples like Battlefront Dasher and Ramcart. It also continues to remain useful once you have an Auric Bank in play to buff the minotaurs. Hidden Garrote helps stop Plunk and Direwood Pack. Eavesdrop, Devouring Shadow and Nullblade offer many ways to stop void recycling decks. Or you can use Souleater Blade to steal troublesome units. Belltower Shot is great for preemptively removing key cards and breaking the opponents game plan, or simply providing another way to kill a unit once it is in play. Petra can grow pretty strong since we have so many spells that we play early on. Try to hold off playing Golden Horn Security until you can unleash it for at least 2 copies.
If you want to increase your odds of having 3 Shadow infuence to play Display and Nullblade early in the game, you may want to swap out some of the factionless power cards for regular sigils.
