So I have a question I wanted to ask for a really long time, What does the card mean exactly when it states "The next time you woul take damage"? Is it saying that I would need to take damage once before I cast the card and then the eff kicks in the second time I would take damage? Or is it saying that the damage would be reduced the next time I take damage in general Ex: At the start of Bp while I have no monsters on the field while my opponent has 2 monsters on the field and I cast this, will I be able to reduce the damage I would take when my opponent attacks me from the first monster's attack? Or will the damage be reduce on the second monster's attack?
