Question on targeting

[L_O_L]

When a card like Dragon Fangs comes back from the graveyard, does it actually target the creature you just played ? For example, can it be attached to a creature with protection from green in that situation ? The relevant rules text has been boldfaced.

Dragon Fangs [1G]
Enchantment - Aura
Enchant Creature.
Enchanted creature gets +1/+1 and has trample.
When a creature with converted mana cost 6 or more comes into play, you may return Dragon Fangs from your graveyard to play attached to that creature.

I ask because it doesn't specifically mention the word 'target'.

Thanks !

Auras put into play (by either this effect, or Enduring Ideal, or anything else that puts enchantments into play) have to go on something.

Since the aura isn't cast in this case, there is no target. It just goes on something.  Dragon Fangs would go on something with cmc 6 or more that just came into play, unholy strenth would go on any creature, etc.  Yes, you can even put these auras on creatures with shroud.

But protection from green specifically says any enchantments/equipments that are green die immediately.

So dragon fangs could go on Emrakul or Inkwell Leviation, but not Progenitus.

Thank you for clearing this up LotusHead !

It doesn't die immediately, it can't go there at all.  A creature with Protection from Green cannot be enchanted by a green enchantment.  The enchantment would just stay in the graveyard, not moving at all.
