Donate at end of game
The game designer intends that &quot;after this turn&quot; effects do not happen when the game ends. The game ends at the end of your turn, so any other effects set up after that can't happen: nothing happens after the game ends. Likewise if you have five Possession effects stacked up for &quot;after this turn&quot; but the game ends, you of course do not play those turns.
