Sinistcha w/ Teal Mask Ogrepon ex

This deck is built around Sinistcha and Sinistcha ex, whilst using Radinat Greninja and Teal Mask Ogerpon ex for draw power. The main function of this deck is to use search cards like Bug Catching Set and Earthen Vessel to grab energy from the deck, then discrading it using cards like Professor's Research, Ultra Ball, and Radiant Greninja's ability, to charge up Sinistcha ex's "Re-Brew" attack, which putch 2 damgae counters on one of your opponent's pokemon for each grass energy in

This deck is built around Sinistcha and Sinistcha ex, whilst using Radinat Greninja and Teal Mask Ogerpon ex for draw power. The main function of this deck is to use search cards like Bug Catching Set and Earthen Vessel to grab energy from the deck, then discrading it using cards like Professor's Research, Ultra Ball, and Radiant Greninja's ability, to charge up Sinistcha ex's "Re-Brew" attack, which putch 2 damgae counters on one of your opponent's pokemon for each grass energy in your discard pile (the attack also then shuffles the enrgy back into your deck). If you manage to get 18 grass energy in your discard pile, Sinistcha ex will put  360 damgae on one of your opponent's pokemon, which almost a guaranteed  knockout. In the early to mid game, however, you probably won't be able to do extreme amonuts of damage with Re-Brew, which is why the non-ex Sinistcha is your early/mid game attacker, discarding up to 3 energy from your pokemon, then doing 70 damage for each energy discraded. You can easily get energy into play with Teal Mask Ogerpon ex's ability, which attaches an energy to it and drwas you a card. The Ace Spec in this decklist is Secret Box, which searches your deck for one of each type of trainer card, in exchange for discarding 3 other cards from your hand. If you don't want to play Secret Box, then I would suggest Unfair Stamp, as Sinistcha is likely to get knocked out very quickly. I would also suggest playing Iron Leaves ex as a backup attacker, however Sinistcha is pretty efficient on its own. This deck doesn't do incredibly well against any decks running Iron Hands ex, Although it a type adavantage over (tera dark) Charizard ex and Cornerstone Mask Ogrepon ex. Thats really all I have to say about this deck, please comment if you think there are some card(s) that you think would synergize well with this deck, and note that this deck is for somewhat semi-competitive play, and wont be seeing play in large competittive tournaments any time soon.
