I am surprised this deck is not on SE forum as it is the strongest meta deck now.

There are various versions but the strongest one takes on a toolbox approach imo.

Hero: Darkclaw

Allies (12):
4x Bloodpack Shaman
4x Wulven Prophet
4x Wulven Tinker

Abilities (18):
2x Midnight Howl
4x Blood Moon
4x Captured Prey
3x Speedstrike
1x Mark of the Feared
1x Vision of Endia
1x Acid Jet
2x Confluence of Fate

Items (7):
2x Pathfinder's Machete
2x Jeweler's Dream
1x Spectral Sabre
2x Lythian Sledgehammer

Locations (4):
4x Lakmire: Training Outpost

= 42 cards

The main combo is Prophet + location that you can play any attachment for free from your deck.

Since you can search any attachment its best to take on a toolbox approach so that you can answer different situations.

Speedstrike, Midnight Howl and Captured Prey are the staple attachments for DC. Confluence of Fate is you draw engine that you want to play as early as possible. Vision of Endia is for removing Viska and Kion. Mark of the Feared is for early board control or you can attach to your own prophet for some late game damages.

Pathfinder's Machete has excellent value when you have location on board. Jeweler's Dream is an alternative if you don’t draw location early. Spectral Sabre is for removing A Legend Rise or served as a back up weapon.

Seek is such a powerful ability and it’s even stronger when combined with the location. Hope the Design Team will take a look on it and balance on the next patch.
