When a card’s text box has multiple effects, you resolve them in order from top to bottom. When multiple players use cards with ability simultaneously, start with the player whose turn it is, and proceed clockwise around the table.
Example: There are 4 players in the game. You use your Curse Witch card. You start resolving its ability with the player to your left. If during this time the Curse cards run out, the remaining players don’t have to take a Curse card.
