Tsunade growled at what happened. But she had to work with what she was given. "I'll summon Plasma Eel(Atk:500/Def:1200) in attack mode. I will use it's effect equipping this monster to any face up monster my opponent controls. That monster can't be tributed and it loses 500 Atk each my opponent's end phase. I will attach Plasma Eel to Yami's King's Knight." With that the eel wrapped itself around the Knight. "With that I end my turn." With that she awaits the fate of their monsters or Life Points. 

Cora seems to think about but decides to make her offer. "Maybe...I could go with you? If it's calling you, maybe it's a spirit that needs help?" She wonders.
