The Blue Eyes White Dragon Global ability states, "Pay bolt and knock out one of your monsters to reduce the cost of the next die you buy by 2 energy".
I ~think~ I know the answers to my question but just want to be certain.
Question 1) If this ability is used during my opponents turn, or during my attack step, does the effect last until my next main step? I know effects generally don't last beyond the end step, but I believe previously all effects have targeted dice/characters. I wondered if this one, since it affects the player and refers to something that can only be done in the main step behaved any differently (and since the global would be infinitely more useful if it lasted beyond an end step).
Question 2) If the ability is used twice, knocking out 2 of my own characters, my next die purchase would be reduced by 4 correct? (as long as that does not take the total below 1)
