So your argument for the philosophy being flawed is just Oryx biting off more than he can chew (regardless of philosophy, he will always lose anyway because he is the antagonist and we are the protagonist in a conventional hero story)? Either was fine with dying (he says so in the end of the Books of Sorrow), and to him it just means he wasn't worthy of joining the final shape. Oh, I just remembered that a card suggested that Oryx' intention was to lose, and that the construction of the Touch of Malice is his true claim to immortality.
