There's not much of an upgrade for BWGX deck as we want to keep the key cards to make this deck work. There has been a lot of Greymon stuff released for both WG and BWG, so we have too many choices to choose from to build this deck. Although for BWGX, I am mainly using the cards from BWGX deck, so not much of a change even if I added cards from the LM Set. I did have to reduce the numbers to fit the cards.
