Good fight, but Colleen should take the majority. Don't forget that when she merged minds with Iron Fist, she got his knowledge of martial arts and chi transferred to her, and she was already a skilled swordsmen in her own rights. She's peak human and can further enhance her strength with chi. The only question is whether or not Colleen's sword can go to blows with Soultaker without getting broken, but considering it is a notable sword that ismore than 1,000 and not just a random katana, I don't think that should be a problem.
