Netrep Q&As
Q: If I equip “Fusion Sword Murasame Blade” to “Spirit Reaper,” would “Spirit Reaper” be destroyed or would this be an illegal activation? A: You wouldn't even be able to target him with it at all. “Spirit Reaper” is not a Warrior. It would be an illegal activation in this case. If “Spirit Reaper” were turned into a Warrior through “DNA Surgery”, equipping “Fusion Sword Masamune Blade” to “Spirit Reaper” would cause “Spirit Reaper” to destroy itself through its effect.
