Question

77 – 1. When resolving an effect like Caliban’s, “discard cards from the top of your deck until an … is discarded.” Is the whole discard simultaneous, such that a response to any particular card being discarded would trigger after the whole discard effect, or are the cards discarded sequentially, such that a response to any particular card being discarded would trigger after that card is discarded but before the next card is?

2. If I’m resolving Caliban with no allies left in my deck and discard Jackpot, can I trigger Jackpot’s response, shuffle, continue discarding until I discard Jackpot, trigger its response, shuffle, continue discarding until I discard Jackpot… on and on until Jackpot is the last card in my deck? (at which time the deck will reshuffle with Jackpot in it and Caliban will stop discarding.)

3. I control 2 allies, one of them being Pinpoint. I play Caliban and trigger his response. I discard White Fox. Can her response trigger immediately? This allows me to put her into play, discarding Caliban from play because of the ally limit, trigger (and exhaust) Pinpoint to shuffle Caliban into my deck, then continue discarding until I discard Caliban himself. Or does her response have to wait for Caliban’s whole discard effect to finish, in which case this play is not possible?
