Forum:Xyz Fusion?

To one and all Supposed I had a Elemental HERO Neos, two Honests on the field, a polymerization and a de-fusion in my hand. I Xyz Summon Evigishki Merrowgeist What if I use Polymerization in Main Phase One to Summon Elemental HERO Absolute Zero, then use De-Fusion on it to get back Merrowgiest and Neos and it destroys all my opponent's monsters. When this happens, does Merrowgeist still have it's two Xyz Materials?
