  Official Ruling
  It determines what enchantments to return when its resolution starts. If more enchantments go to the graveyard during the resolution, those additional enchantments are ignored.
• WWizards of the Coast2005-08-01
  Official Ruling
  Auras can only be placed on permanents that were on the battlefield before this effect started to resolve. You can't put an enchantment onto the battlefield with Replenish and put an Aura that is also entering onto one of those enchantments.

  Official Ruling
  You must return Auras if possible, even if this means enchanting an opponent's permanent with a good enchantment.
