I want to see a cycle of identifiable funghi for Seekers.
I'd also like to see lots more Parley cards, and a Parley investigator (maybe Charlie Kane?).
For example, Mystics could get Word of Command, which parleys non-Elite Monsters into becoming an asset for you. Rogues could get Swindle, which parleys enemies to exhaust them and gain resources. Survivors could get Buying Time, which parleys enemies to pull item assets from your discard pile.
