Undying pillar of flame

[JustAWalrus]

If my opponent casts pillar of glame on my {hound of griselbrand} does it come back. Undying says if the creature died.

No, it doesn't. If Pillar kills the creature, it replaces dying with being exiled. The creature never dies, so undying never triggers.

Thank you

Think of it as, the flames destroy there body. Then the flames destroy the ash too. There's nothing left to come back
