Roaring Moon and Dedenne

Very creative idea! There are just a few things that I would change. First off, there're WAY too many energy cards. 12 at most, and that's being generous. I'd invest into Luminous Energy (Paldea Evolved) to make energy costs more accessible across the two types. You should also use a different energy acceleration other than clefairy. Personally, I'd run a 2-2 line of Xatu (Paradox Rift) to both accelerate energy and draw some extra cards, something that this deck also lacks. Four bosses is way too much, so I'd run about 2-3 to make room for some of the other cards I'll soon suggest. You can remove two of your researches, and put in two Iono (Paldea Evolved) in to compensate. Peony doesn't really need to be here, as it eats your supporter for the turn and leaves you with a small hand if you don't have a means of more card draw (which you don't at the moment). This deck also needs Manaphy/Jirachi, as you'll be playing with fire by leaving so many Pokémon at low HP, so it would be easy pickings for spread decks. Lastly, you need to consider that your opponent is very well able to just KO the 30 HP Roaring Moonon the next turn, which will leave you with no out, as the rest of your deck relies on it. So, great idea, just needs a bit of work to function.

Oops, totally didn't mean for this deck to be public, but I'm glad I did because that is very helpful advice! Thanks so much CountyGibbon798 !

Galyte No problem, even if it is entirely on accident lol. (I also noticed now that this deck is running Leafy Camo Poncho without any VSTAR/VMAX cards, so you may want to do something about that, too.) Hopefully this can be used to help make better decks in the future!

omg, you're right CountyGibbon798 , Leafy Camo Poncho doesn't protect Roaring Moon 💀 LOL hmm I was trying to find a way to protect Roaring Moon from Boss' Orders, especially while he has low HP. You wouldn't happen to have a good way to do that would you?

Galyte I know that there's Diancie (Astral Radiance) that works, but you'd still need a way to switch Roaring Moon out after attacking so it doesn't immediately be revenge KO'd. Again, assuming that you do get it onto the bench, something like Manaphy is a requirement to prevent bench sniping.

CountyGibbon798 That's a good suggestion! Bummer that Diancie's ability only works in the active spot. I think I will stick to using Manaphy and Jirachi together and see how it fares. Thank you for your help!
