Munchkin Apocolypse: Temporary Respite

[MunchkinMan]

Generally, you can't play cards in response to other cards because that's not how the game works. For a card to be played like that, it has to say it can cancel something (e.g., Presidential Proclamation can cancel a disaster, as can a character with the Militia Class by discarding two cards). If a card says to open a Seal, then you open a Seal, resolve the Seal's effects, and then you can play something. Of course, if the Seal says to open another Seal, then you have to wait for that Seal's effect to resolve before you can play something, and so on. If you want to prevent the 7th Seal from being opened in the scenario described, you'd have to play Temporary Respite before the effect that opened the 6th.
