so, for a bit of background, St. Louis regionals format will be ultra prism. But, keep in mind, no solgaleo. http://www.pokebeach.com/2017/11/alolan-diglett-and-dugtrio-from-sm5 Pokemon(17): 3 Alolan Diglett SUM 3 Alolan Dugtrio ULP 3 Staryu BPT 3 Starmie EVO 3 Tapu Lele GX GRI 1 Mr. Mime BKT 1 Espeon EX BPT Supporters(13): 3 Professor Sycamore 4 N 2 Cynthia 3 Guzma 1 Brigette Items(13): 4 Ultra Ball 4 Energy Retrieval 2 Choice Band 2 Field Blower 1 Rescue Stretcher EDIT: Stadiums(4): 4 Mount Coronet Energy(13): 13 Metal Energy Deck Idea: This has a very good gardevoir gx matchup, which I like. The goal is to take big hits with one prize attackers for a positive prize trade. Card Choices: Mr. Mime-This deck will have a lot of toruble with even one Tapu Koko without it. The resistance to metal on Tapu Koko makes you discard 5 energies for a OHKO. So, for the amount of low hp pokemon you run, you need Mr. Mime. 3 Sycamore, 4 N, 2 Cynthia-This is one I could have easily changed. I just think the power to effect your opponents hand is incredible. The Sycamore/Cynthia split is because thinning your deck is huge, but saving resources is too. This gives me many options when deciding on my supporter for turn. No Float Stone-At this point, when you are attacking for 0 energies, I think you can use your attachment when you need to retreat. Yes, it's one less energy you can discard, but float still isn't worth the spot. Matchups: Gardevoir GX: 90/10 - Because of weakness, this matchup is amazing. You are trading OHKO's with them even with gallade. And you have a one-prize stage one and they have a two-prize stage two. Golisopod GX/Zoroark: 55/45 - This matchup is close. Although, because of the prize trade. Dugtrio is slightly favored. Silvally GX/Metal: 70/30 - In this matchup, they will usually have trouble keeping up with quick, big hits. But, it is definitely winnable for them. But, usually this is favorable for Dugtrio. Volcanion: 25/75 - They can just use baby volcanion. It will be an even prize trade, where they just need to do less work for knockouts and whiff a lot less. It is also a basic against a stage one. Because of this, they are favored majorly. Greninja BREAK: 40/60 - This matchup can go either way, but usually they should be able to start spreading and take prizes faster than you, but other times, you can take prizes to fast and out-pressure them. Drampa GX/Garbodor: 65/35- This is favored. Unless they can stream garbodors fast without you taking prizes first. You can outpace them and take all 6 prizes faster. Let me know what you all think. Feel free to suggest any card changes.
