If my opponent use whatever card effect to reduce my attack's damage to 0 and decided not to block, I can still respond with my Holding Ground during the damage step to return the damage back to the printed damage of my attack card (of course, if it has a value other than 0).
If my opponent half block my attack, I can respond with my Holding Ground during the damage step to make the damage dealt equal to Half printed damage rounded up.
If my opponent reduced my attack's damage to less than its printed damage, can I wait until they respond with Cutting Edge to reduce the damage by destroying their foundations and then I respond with my Holding Ground to make them take more damage? Or its already too late once they use Cutting Edge's effect?
Thanks.
