Does Tigra's or Invisible Woman's card cancel an Ambush effect for every player, or only the player who discarded it?

Question

Accepted Answer

Both cards cancel the Ambush effect for every player. The 'instead' wording, and Ambush effects that do not target players, show that the cancel applies to the whole Ambush.
