My work in progress warhelm aggro deck. I like going all in on synergies that run through a decklist and warhelm decks are no different.
The To Craft list boils down to 4x Highland Sharpshooters to go all in on abusing the warhelm/empower mechanics.
The deck plays quite aggressively. You want to go face as soon as you can, dumping your 1,2, 3 drops onto the board, triggering obscene amounts of warcry and/or lifesteal and spewing value onto the table all day.
Currently, I have Rolant and Kaleb in Marchants for a tutor-able fatty for reach at end of game (they're available from tutorial) but they will likely get subbed out for Deepforge Plate and something else more effective. If things go as they should, you shouldn't even get to having 8 power live on board.
Navani is also only included simply because she was gifted from a dual deck included from the starter bundle. She isn't ultra-effective but it's a new toy and I wanted to try it out.
