Ardent 10 with dominant ideal, recharge, and the right powers is effectively out of the time stream, and further has effectively infinite actions, and more so infinite actions that can interrupt anyone else's actions. Not a win, and between his metamind and all powers known/recharge through spells and feats, Azrael can do just as well if not better, but it's effectively a stalemate, as the Ardent will always exist in some time stream somewhere/somewhen, so he never really can die. Do it as an Elan, and he can do so infinitely, given that he won't die of old age.
