I read on the last post that there had been demands for an expansion of the Stash. I had a thought and wanted to share it. A limited sideboard is one of the hallmarks of the game, and important for balance purposes. My proposal is:
Each party gets its own Sideboard (renamed from 'Stash' to 'Sideboard.' Those sideboards are unique to that party and that campaign.
A new tab, "Trove," is created, and at any point between adventures, players may move a card (like the Robe of Runes, or Amulet of Mighty Fists) from their party sideboard to the Trove. Trove becomes the mechanic for trading cards across parties, while the sideboard remains for those situational cards that you may not want in your deck full time.
Thoughts on my thoughts?
