Can I use another card's ability in the middle of a 2x Exchange or a draw of two cards?
The rulebook says you must finish a special ability before using another card's, and the publisher and several posters agree.
No. Finish one special ability before you start another. Nothing can be slipped between the two exchanges of a 2x Exchange or between two draws of one ability. You may end an ability early by taking fewer cards, but you cannot interrupt it.
