This question already has an answer here:
Enchant Creature Creatures you control that are enchanted get +1/+1 If a creature you control that's enchanted would die, return it to it's owners hand instead.
Is that a +1/+1 counter? Or is it just a modification to the P/T?
Also, given the language it reads as if it means to say any creature enchanted by any enchantment. Correct?
