The Wish spell is one of the most powerful spells in the game. It ignores all cards that state they are immune or otherwise unaffected by spells unless they state an immunity to the Wish spell. Regardless of a champion’s immunities or special powers, Wish can discard them (unless a champion’s special power states that it is immune to the Wish spell itself).
The Wish spell is not a counter-effect spell like Limited Wish; it can’t be used to negate most events. It can only be used to negate an event with a stated duration (like events that last “until the player’s next turn”). It can’t be used to stop events like Caravan or Cataclysm! since those cards’ effects are instantaneous.
