Ruling Umbreon UD/Espeon Prime UD Question

[chemeleon428]

I had thought of a tech to counter Vileplume, using Metagross LA(irrelevant to question, if Professors need to know) to bring up 'Plume, and then using Espeon Prime to attack it for a possible KO, them being immune thanks to Umbreon's attack and Espeon's Pokebody.

Now testing this against someone, they said that the immunity from Umbreon wouldn't work, because Moonlight Fang reads "damage to Umbreon", however, Espeon's Pokebody reads "Espeon can use the attacks of all Pokemon that evolve from Eevee as its own", but went ahead and said it would count, just incase, as long as I found out for sure, since my argument was just as valid.

Long Story Short, would Espeon Prime be immune to attacks from Pokemon with Pokepowers and Pokebodies if it used Umbreon's Moonlight Fang because of its Pokebody, assuming it has one Darkness Energy attached to it?

Also, thanks to Dragon Expert for helping me out yesterday with Dialga G, assuming you read this.

The immunity effect would work because when it says damage done to [insert Pokemon's name], it is to be treated as damage done to this Pokemon. Your welcome for helping you yesterday.~Mark

The answer is yes.
If a Pokemon attack is copied by another Pokemon - in this case by Espeon Prime's Poke-Body, any instance of the attack which is self-referencing, just replace that Pokemon's name with "this Pokemon".
Moonlight Fang is self-referencing; therefore, if another Pokemon uses it, it gains the effect instead of Umbreon for that turn.
