Ehrlich? Ich dachte First Strike Damage und normaler Combat Damage werden zwar zeitlich kurz nacheinander ausgeteilt, aber dennoch im selben Moment im Spiel.
510.5. If at least one attacking or blocking creature has first strike (see rule 702.7) or double strike (see rule 702.4) as the combat damage step begins, the only creatures that assign combat damage in that step are those with first strike or double strike. After that step, instead of proceeding to the end of combat step, the phase gets a second combat damage step. The only creatures that assign combat damage in that step are the remaining attackers and blockers that had neither first strike nor double strike as the first combat damage step began, as well as the remaining attackers and blockers that currently have double strike. After that step, the phase proceeds to the end of combat step.
D.h. du bekommst sogar noch Priorität zwischen beiden Phasen.
