I've tested this deck multiple times, and almost half the time, by the second turn I'm attacking with Regidrago vStar. You can do this by getting Reshiram into the active and Regi benched. Attach to regi with reshiram's turboblaze. Get Wally into play for the Drago vStar. (compressor than vs seeker to get it) Attach dragon energy for turn, and regidrago is all ready with attackers in the discard pile thx to compressor. If you can't pull it off, you have dedenne gx and legacy star to get the cards you need. But your hands for the rest of the game are hard to expand.
