I, for one, would like to discuss specifically the removal of Elixir Potion in favor of adding Ancient Potion, and how this affects Ironclad's viability against the Repulsors (?) who add Dazed to your deck in The Beyond, among others. (Wound, Sear)

However, please use this thread for all relevant discussion related to this set of changes. :)
