I finally did get a chance to make my hypothetical Gyrados/Weavile Deck, though the decklist doesn't quite match what I posted earlier: Pokemon: 19 3x Magikarp (MT) 4x Gyrados (MT) 4x Sneasel (DP) 3x Weavile (SW) 1x Weavile (DP) 1x Pachirisu (GE) 3x Manaphy (Various) Trainers: 22 4x Rare Candy 4x Sidney's Stadium 3x Professor Oak's Research 2x Switch 1x Dual Ball 1x Felicity's Drawing 1x Night Maintenance 1x Mr. Stone's Project 1x Super Scoop Up 1x Bill's Maintenance 1x Leftovers 1x Steven's Advice 1x Copycat Energy: 19 8x Water 4x Dark (Special) 2x Holon WP 2x Scrample 2x Cyclone 1x Double Rainbow Basic Strategy: Use Weavile to grab darks,for Gyrados, then Dark Engage Gyrados to add extra damage. Sidney's Stadium prevents Gyrados from confusing itself when combined with Dark Engage. It's really a shame Rainbow Energy isn't legal anymore. Basically, the energy and trainers need a fair bit of cleanup. I'm open to suggestions.
