It's a cool concept but I have difficulty seeing you find room for it. The sheer amount of resources Lugia requires to get set up is tremendous, and you'll only really get 1-2 attacks off with it before it's either KO'd or you don't have the Plasma required to use it. Lugia, I'm afraid, doesn't really have a place this format as Plasma decks only really get good next format. You're probably better off just going with the main strategy of the deck then adding something that may require 5-6 spaces.
