Embrace the Shadow

Time for another mono-color deck and this time is mono-shadow. Mono-shadow's big boy legendary is Tasbu and although I've always pictured shadow to be more of a controlling faction, Tasbu basically rewards going wide and playing units so I thought: "Hey, shadow actually has a lot of efficient aggressive 2 drops" and built this deck to capitalize on that. Combined with Shadow's good removal, you have a deck that can clear blockers and constantly push pressure on the opponent. Tasbu makes combat and removal (especially board wipes) a nightmare for the opponent and Memory Dredger helps you bring back all your little good 2-drops when they eventually eat it.

Market
Dark return brings our best unit back for round 2.
Malediction is a nice boardwipe when the board is full (super unfair with a Tasbu out).
In Cold Blood is extra removal with a nice bonus to deal with pesky justice units (looking at you Makto).
Nullblade is new but it's pretty nice mainly for being a good weapon that control decks packed with removal have a hard time dealing with. It's -5/-5 effect is kind of whatever in my experience, but hosing random dark returns/haunting screams could be relevant.
Bloodlust looks weird, but trust me, this card is an absolute blowout. Killing people with their Mokhnati/Sediti/Rost/*insert big scary here* after you chipped at their health total steals you games.

Like my mono-justice deck, Veteran Mercenary is mainly for fun so feel free to swap that out if you want (although getting random garbage is good to throw away with the market). Nullblade, Impending doom, Shadowland tyrant, Dark Return, Umbren Reaper, and even Devour are all cards that can probably be subbed in for him.
