Sleep

You don't need Psychic and Grass energy. Your only attacker is Jynx. You also have no energy acceleration. I like the Venusaur line for this deck, but you really don't need Hypno if you focus on Venusaur. If you use Venusaur you should cut it to a 3-0-3 line instead of 4-0-4. You could also add a 2-0-2 Baxcalibur line with the rare candy to consistently accelerate energy. There's several options with this deck, and while two of them are redundant, if you just focus on Venusaur this could be a pretty good deck.

Thanks for the feedback Tangent. Appreciate it, let me know what you think of the new distribution.

4 Candice feels absurd to me (you don't need any) and Emergency Jelly doesn't seem to do too much. Healing is not a game winning strategy. I also don't like Crushing Hammer. I get that you want to play Arven, and that Bravery Charm gives Jynx some much needed bulk against cards that struggle to hit above 220/230, but you should add a Lumineon V so you can run FSS. You don't want Switch Cart. Instead I think you go for Escape Ropes, and possibly switch. Ryme could also be a good draw supplement. I'm not sold on Baxcalibur for energy acceleration, but I'm not sure another option exists, barring Archeops (can accelerate special energy for Jynx and attach a water energy for turn). I believe that your main issue is a draw engine. Since you have bench space, the Skwovet/Bibarel engine would work well (would consist of a 2-2 Bibarel line and a Skwovet). I'd also suggest dropping professor's research completely in favor of an ability based draw engine. An Arezu could be swapped with a fourth Ultra Ball. With an ability based draw engine and more gusting effects, this deck seems like it could be pretty solid. I like what you've done, now you just need to fix a few holes and focus it more. (Also if you want me to see the deck, I recommmend pinging me with @.)

Thanks for your feedback on this.

I've played around with your suggestions and added in a few more cards. I decided to go with a single Archeops line and chucked in two Ryme's as well. I don't want to go too heavy on swapping out my opponent's Pokemon as that would undo any sleep effects that are currently occurring. I also decided to keep with switch cart rather than escape rope as escape rope is an "E" so I would like to prep this deck for any upcoming shifts.

Pretty happy with how this is sitting now but still keen to hear any further thoughts you might have.

You won't really worry about undoing sleep as you will ideally attack with Heart Stopping Kiss every turn. I was also just randomly saying stuff when I mentioned Archeops as an alternative to Baxcalibur. I think you want to focus on Bax, and that you need an Earthen Vessel or 2 to make it work. Switch cart doesn't work though, if your opponent gusts up a Venusaur, Baxcalibur, or Bibarel. It should be a switch if you don't want to use Escape Rope. You may want to run some stadiums in case your opponent plays Pokémon League Headquarters. Path would be an obvious choice, but it has an E stamp so you could consider Artazon or any other stadium you believe would work. That being said, this deck looks pretty much ready to run!

Final iteration, thanks for all of your help.

Now I just need to track down these cards.
Easier said than done for someone based in NZ haha

This looks beautiful. Will test on LIVE and let you know of any edits I make. Also if you manage to build this before rotation have one switch as an escape rope until it rotated. And for all we know it gets reprinted in Temporal Forces. Good luck and have fun!

Cheers for all the help on this, any feedback from having tested it yourself would be great.

I'll be doing an update of this deck come the release of Temporal Forces.

I removed the Bibarel line and Skwovet as well as the Arvens and Bravery Charms in order to add a 2-0-2 Pidgeot ex line, a Rotom V, a Clavell, a Hisui Ball, a Lost Vacuum, another Artazon, and an Atticus. I would also recommend swapping the current Frigibax for the new one with collect. Also, all of the Bulbasaurs in standard are functionally equivelant without Grass energy, so I'd recommend running whichever one you have on hand.

I'm excited to see what shifts with rotation, especially with the addition of Buddy Poffin!

Good luck with getting your cards.

I've found that in my testing, I need to use Pidgeot as an attacker to take down some smaller targets, like Comfey, or basically anything under 100HP (because I quick search for double turbo, attach to pidgeot). I also find that coin flips suck and that you should just build a different deck if you hate relying on coin flips. I once whiffed 4 times in a row, and I nearly lost my mind. Anyways, good luck!

wait roaring moon ex is literally so unaffected by this deck, but there is a solution:
add lost vacs so you can get the booster capsules out :)
