Suggested by iKnowledge Rand has returned, but now he is up against a very clever mastermind. Xehanort has orchestrated a bunch of events even while he was dead. That certainly takes a genius level intellect at the very least. Rand is very skilled though and his channeling abilities are second to none. The whole fight could be over in a single turn once both combatants have thought of the optimal outcome. I believe Xehanort would have the edge though. His magical abilities are top notch and he can also fight at close range. Rand would ultimately be overcome. Xehanort wins.
