My take on Lugia Vstar (Expanded)

Use your summoned archeops(s) to accelerate energy onto reshiram and yveltal to to huge chunks of damage with out losing many prize cards; and use cross switcher to get whatever matchup you'd like against your opponent. The Amazing Yveltal is excellent for taking out really tanky cards, like other Lugia vstars or V-Union cards. It is expanded, so you might have a hard time finding somewhere to use it competitively.
