Does a non-creature God entering the battlefield trigger Pelt Collector?
Pulling from a ruling on Nylea, God of the Hunt:


  When a God enters the battlefield, your devotion to its color
  (including the mana symbols in the mana cost of the God itself) will
  determine if a creature entered the battlefield or not for abilities
  that trigger whenever a creature enters the battlefield.


So if you don't have enough devotion for Nylea to be a creature, it doesn't trigger Pelt Collector.
