In my previous campaign, we had a segment with the deck of many things. My character drew the card that gave him 3 wishes. Next character drew a card and it was bad, so I wished he could have stopped that other character from drawing from the deck.

DM decides my character's wish puts him back at the beginning of the scene, so he gets to draw the card with 3 wishes again.

Spent the rest of the campaign very carefully choosing what to spend my 5 wishes on.
