原文Muster the Departed doesn't need to have been on the battlefield when the creature died. For example, if a creature dies during combat on your turn and you cast Muster the Departed during your second main phase, its last ability will trigger at the beginning of your end step.
原文Muster the Departed's last ability will trigger only once during your end step, no matter how many creatures died under your control this turn. However, if no creatures have died under your control so far this turn as your end step begins, the ability won't trigger at all. It's not possible to cause a creature to die under your control during the end step in time to have the ability trigger.
原文The new token doesn't copy whether the original token is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, color, and so on.
