Idk if anyone plays this game, but Absylonia's Panacea ability moves Warbeast cards to your "deck." I couldn't find clarification on which deck tho, Army or Reinforcements. Does anyone know the answer?
I don't think anyone does. The subforum was dead for months (years?) before PP put it out of its misery in The Great Purge. It's weird that they're potentially drumming up interest by bundling it in the AIO boxes - I don't believe they have any plans to keep producing it. People could report their renewed interest on the forums, except there's no place for it, so anywhere you post would be offtopic and get modded into oblivion. I am not bitter about PP's attitude.
To answer the question, I believe an unqualified 'deck' would mean your army deck, since that's the primary deck you'd interact with. They would be specific about the reinforcement deck.
