Ruling Dexoys and rayquazza legend

[thepliskin5005]

Im just verifying this question if you attached devoulter on Dexoys rayquazza legend and devolved a pokemon and knocked it out would you still get two prize's. A while ago i asked a question about can you use a call energy on Ho oh legend and you said yes you can but you didn't take in acount that the call energy turns in to a fire energy with its pokebody.

The reason you can still use Call Energy on Ho-Oh is because Ho-Oh just changes the type of Energy it provides; it doesn't change any effects.

In regards to this Devoluter question, the answer is no, because of two reasons:
1) Devoluter is not one of R+D LEGEND's natural attacks. It says it can use this attack instead of its own, but it's still not an attack native to R+D LEGEND.
2) Space Virus Poke-Body states that for this to take effect, the Pokemon must be Knocked Out by damage from an attack. Devoluter does not deal damage.
