If they fit, definitely! I'm looking for trainable Raikou and Celebi for a long time now. :]@vini, no offense mate, but in the past people ask me that, and even if theyre good they just say okay :)
so if the natures/iv's fit what you want will you actually make an offer? (:
edit: @adam, I dont have non-shiny one's so I can trade one of my shiyn dogs for the shiny lugia o.O
