Essence of the Wild question

[entropize]

Alright I know that any creature brought out becomes a copy of essence of the wild, but say you summon Purphoros, God of the Forge with not enough red cards in play while essence of the wild is in play. My question is: does Purphoros, God of the Forge become a copy of essence of the wild. 

[Jabilac]

At the time that Purphoros, God of the Forge enters the battlefield will determine if he is a creature or not.  If, when he ETB, he is not a creature then he will not become a copy of Essence of the Wild.  Below is the relevant gatherer ruling

9/15/2013   If 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.
