How are the Investigation Doom cards added to the hazard deck?
The Investigation rulebook says to shuffle the Doom cards into the hazard card set, then construct the deck as normal; a player describes it the same way.

Shuffle the three Doom cards in with the hazard cards for your difficulty, then build the hazard deck as normal. They are added to the pool, not swapped for existing cards, so not every Doom card is necessarily in the final deck.
