Lost Kitty (Sablescarada)

Lost Box with Meowscarada ex (Sablescarada?)

I think this one pretty much speaks for itself. Ideally, you are able to set up both Meowscarada ex so that by the time you have 10 cards in the Lost Zone, you can be placing 18 damage counters per turn between your two cats and Sableye. However, realistically, most games you'll only manage to get one in play. Just be sure you don't over-commit your bench! It's because bench space is so tight that I don't play a Radiant Pokémon in the deck, but

It's because bench space is so tight that I don't play a Radiant Pokémon in the deck, but Alakazam is a natural fit. 

UPDATE/EDIT: After playing another dozen or so matches with this deck, my expectations have been far exceeded. About half of those matches were against Chien-Pao ex decks, which this deck matched up well against, despite the fact I didn't have Manaphy in the original build, which allowed Radiant Greninja to feast on Comfeys. So, Manaphy is now in. Echoing Horn is out (as it's more of a luxury than necessity).

I also dropped 1 Nest Ball and 1 Ultra Ball and put in two Level Balls. While the deck functioned well enough with the 3 Nest/Ultra Balls, using an Ultra Ball to grab any Pokémon other than Meowscarada ex often stung, cause there aren't all that many cards in the deck that you don't mind discarding. Plus, between all the Flower Selecting and Colress's Experiment plays, there's a great chance you'll draw at least one of you're Meowscarada ex. So, 3 Ultra is probably a bit much and I might drop it to 1 and add in a 3rd Level Ball or a Hisuian Heavy Ball. Level Ball can go fetch every Pokémon in the deck except for Cramorant and Meowscarada ex and is especially clutch for getting Floragato (which I used more than I thought I would. Likely because the deck doesn't play a Supporter like Irida or Arven that can go get a Rare Candy from the deck) all without needing to discard anything.

Lastly, I'll admit that when I think about what Pokemon types one should play to capitalize on the type weaknesses of the most prominent/numerous multi-prize Pokemon in the current meta, I think: Darkness (Mew VMAX, Gardevoir ex), Fighting (Arceus VSTAR, Miraidon, Regieleki VMAX), and Lightning (Lugia VSTAR, Palkia VSTAR). Grass is an afterthought. However, I learned playing this deck that a few key Pokémon are weak to grass, including: Tyranitar V (played in most Lugia VSTAR decks, of course), Ting-Lu ex (which seems to be the second most popular Paldea Evolved deck at the moment), Darkrai VSTAR and Galarian Moltres V (which are often played together), and, perhaps most importantly (because it's a 3 prizer and is getting a fair bit of play of late in Arceus VSTAR decks) Umbreon VMAX. While this certainly is not a main selling point for this deck, it's definitely worth keeping in mind if you're like me and haven't before paid any attention to grass weak Pokemon!
