"When defending, during the Declare Target step, you may remove your Captain Card from the game to cancel that Attack. If you do this, the attacking ship cannot perform another Attack during that round. This card then becomes your Captain Card with a skill of 3. This upgrade may only be purchased for a Kazon ship".
Can Haliz's text be activated while he is the captain card? (i.e. to cancel a second attack in a later round).
If yes, does the card resolve completely (returning Haliz to captain the ship) or does the act of removing it from the game prevent the last step of the card from resolving?
