Strategy: For turn 1, set up with Smeargle. Use Pokemon communication to make sure the lonely LEGEND halves are in the deck while receiving Bronzong/Feraligatr, then you can better use Legend Box. Smeargle's power/PONT for deck circulation. On turn 2 evolve Bronzong and Gatr, then use the Pokemon Communication/Legend Box/Junk Arm combo to set up LEGENDs and Gatr/Interviewer's Questions to supply the Energy. The end goal is to use KGL to waste cards with a small shot at destroying their bench.
