During this decenario:
When you defeat a Kobold story Bane Summon and encounter an ally. ir you acquire ir, you may display it next to the scenario. "
What happend with the allies displayed at the Ene of the scenario?
Can be used to recreate the characters decks?
Thanks
Yes.
Whilst it's not necessarily obvious, close reading of the Core Rulebook does indicate that cards displayed next to the scenario are fair game for rebuilding your deck; as long as there is no instruction to banish them or otherwise remove them from the game.
From the Core Rulebook, under "Ending a Scenario, Adventure, or Adventure Path"...
Next, if any boons that are displayed or in a recovery pile could be recovered, banished, or removed from the game when a certain condition is met (such as during recovery, at the end of an encounter or a turn, or when a location closes), process them as if that condition is occurring; treat all characters as local while doing this. Then put all non-boons back in the vault. Next, rebuild your deck (see Rebuilding on page 17). Finally, put any remaining cards back in the vault.
Then, from the Core Rulebook, under "Rebuilding"...
After each scenario, whether you won or lost, you must rebuild your deck. Start by combining your discards with your hand, your deck, your bury pile, and any cards you displayed; you may then trade cards with other characters.
