Do discarded temporary Evolution cards go back into the deck, or get reshuffled when it runs out?
No. Once a temporary Evolution is played and discarded, it stays out for the rest of the game, and discards are not reshuffled into the deck, so the deck simply runs out. A few cards, such as Cyber Bunny's, are exceptions. Some groups slide played cards under the deck instead, which the printed rules do not describe.
