When cards are removed, normally or in response, with a necro, what happens to the cards removed in the event of disenchant or bounce? Are they gone for good and can only be wished back?
The ability that removes the cards also sets up a delayed triggered ability that will put the card in your hand. This is independent of Necropotence itself, and is just part of the ability that removes the card (so removing the Necropotence will not affect this triggered ability). It is much like the ability of Kiki-Jiki or Astral Slide; it does something, then sets up the delayed triggered ability as well.
