Alright, then I know how you can win. Using the reiatsu gathering power, gather it and channel it into your body while unleashing full power. That should be enough to throw off the heat sucking thing.
As for the rest of MC's powers, you should go at him head-on, matching him move for move. Your Zan absorbs Spirit Energy, so you should just absorb anything he throws at you and send it back or use it to power your own attack.
Well, he used a technique that's hard to counter. Even I have trouble dealing with it, and my Zan outmatches his, even if he is my Captian.
Could you give me a quick rundown of your Zan's powers? I might be able to help you figure out how to counter him.
