Several revive effects stacking?

[FAJ]

What happens if I have a Dai Oni that has the elixer of life and casts pheonix pyre?

Case abreviation:
A. revives without pyre active
B. revives with pyre active
C. revives with 0 fatigue
D. revives with 100+ fatigue (or whatever he had at death)

1. Keeps dying/reviving with pyre. When 100+ fatigue the elixer kicks in: he revives AC, AD, BC, BD?

2. Dies first time, the elixer kicks in: he revives AC, BC?

3. Keeps dying/reviving with pyre. When 100+ fatigue, he revives as oni spirit: AC, BC?

Does Pheonix pyre last the whole battle, even if he is revived by another method? Does the pyre effect stay when he goes to Oni Spirit?

Is it possible for the Dai Oni to die/blow-up/revive a bunch of times, then, after fatigue, elixer pops him back to die/blow-up/revive a bunch of times, then, after fatigue, oni spirit pops him back up to die/blow-up/revive a bunch of times?
