For this fight we will use cancellation. So basically, if 2 opposing forces have the same abilitie on about the same power level, then they can't affect the other with it. This is to be sure that we don't spend hours debating which would affect the other.
Battle takes place in a barren Universe with no life except for these guys. There is no " what if's ", so basically if one side doesn't have it, then they don't have it. They can use the environment to thier advantages though.
Explain why your side would win. No spamming by just saying one side over and over again without a reason why.
EDIT: Also, no time travel / time manipulation, and no heralds.
