I have been studying the clash at the summit set and found a pretty interesting combo. If you can get out Dialga Palkia legend out with 2 basic metals and a rescue energy with a Heatran lv x on the bench you can mill your opponents deck every turn while ading cards to their prizes. With one of its attacks you can add the top two cards of your opponents deck to their prizes at the cost of discarding all metal energies, but if you have heatran x out you can save them. Then if DPL gets knocked out the rescue energy will bring it back.
