This deck has a few weakness: Marnie after you have taken 4 prizes with two prizes left, bossing your zacian when your behind prize trade, weak starting hand that has four scoops and no balls, choice belt boosted one shot attacks, Avery, the meta decks that can tank your hits, going second is rough even with voltorb, not enough healing, all your heal switches are in the discard pile; which is wayyyyyyyyyyy to early, quickshot.
Agressive tempo deck that needs consistant draws and spam greninja with scoops to see the saucers, while using mews to look for all your items.
Origin Palkia: pray they do not have boss, pray they don't have cologne, pray they do not go first, pray they do not attack, pray they do not have more palkias do work with, just pray in general (especially marnie). You can play around by placing less mon on the field, which is a good strategy against avery plays. But that depends on your board; have you got everything in your hand to hit hard?
Aceus Decks = not sure because I haven't have consistent matches with this deck archetype, but I can imagine it being a shit matchup as these types of decks are versitle and adapt quickly to your play. Being aggressive with turbo is a must, but don't use up saucers; do energy attachments if necessary.
Turbo diagla= pray they don't hit the wombo combo with their another turn bullshit; other than that, steamroll them.
Mew= Just don't go second; you must make sure turn one and turn two are used effectively as you need to dismantle their board by hitting early as possible, while heal when necessary. If they have oriccorio; they can tank hits. If they have melody, they can hit hard early.
Other decks: I don't know any more necessary info for matchups or plays. Pokemon is all about the play in your hand, while rng is a factor, you have to make the plays that mean something to win.
