''combine latios and latias in a proper deck''
I have made a deck with the latias and latios of the legendary collection to, I,m still updating it for minor fixes but I am close.
Here is a link to the thread, Maybe It could help you

Some tips:
# remember that latios needs latias on the bench for its full attaco of 120
# double dragon energy's and double normal energy's are very usefull for them
# you could try to have more then one of them , or use supporter cards like brigette to summon them on your bench.
I wish you good luck with your latios/latias deck,
