So here is my Shadow version of Berserker Boris. It's not tuned yet.

Current Version (40):

1 x Logan Stonebreaker

(0 allies)

4 x Smashing Blow
2 x Enrage
4 x Rampage
4 x Evil Ascendant
4 x Shadow Font
4 x Master Smith
2 x Melt Down
(24 abilities)

4 x Reserve Weapon
4 x Bazaar
1 x Nova Infusion
1 x Snow Sapphire
1 x Violet Thunderstorm
4 x Berserker's Edge
(15 items)

I originally started this solo type strategy with human due to Lily, Reserve Weapon, Boris's ability looked stronger than EA for Shadow, but I've reconsidered recently and will find out after running this deck through it's paces.

Ideally Logan's SE is stored for an ally kill save, when 7SE is accumulated it should be used to hit the hero whilst allies are killed defensively with armour out preferably.

Unlike the Lily version Berserker's Edge must be dug out of the graveyard with Master Smith leaving Reserve Weapon in play and an emergency weapon if needed to be used. Master Smith can also be used to return armour as needed. There are three varieties for the deck depending on the match-up. I still want to work Shield Bash into it somewhere.
