I've seen this deck get hyped around the internet but there's no thread for it here so I thought I'd make one.
There's many different ways to build P-Groudon decks I feel but this is the list I've been playing:
3x Groudon-EX PRC
3x Primal Groudon-EX PRC
3x Carbink (Safeguard)
3x Carbink BREAK
3x Professor Sycamore
1x Hex Maniac
4x VS Seeker
4x Ultra Ball
4x Trainers' Mail
1x Escape Rope
1x Super Rod
2x Mega Turbo
3x Groudon Spirit Link
3x Scorched Earth
1x Shrine of Memories
4x Strong Energy
8x Fighting Energy
Some explanation for the cards:
Carbink & Carbink BREAK: I feel like with the loss of Korrina for consistency and Robo Subs to hide behind, the defensive / stall build with Wobbuffet no longer works. Instead we can make use of Carbink's Safeguard ability which keeps him safe against both Giratina, Mewtwo and Rayquaza, who are forced to Lysandre something else out or draw deep for a Hex Maniac, for a 1 prize Pokemon. Carbink BREAK's attack gives the deck great speed, which helps it compete with faster decks.
Shaymin-EX & Hoopa-EX: As mentioned previously I feel that with Korrina being rotated, the deck took a big hit to its consistency that can only be made up for by using Hoopa and Shaymin to get some speed into the deck. The downside of course being that the opponent now has 2 easy Lysandre targets, but it's not impossible to try and fit a Parallel City in the deck to help with that, while also making the Rayquaza match-up easier.
Zygarde-EX: Honestly I'm not too sure if I'll end up keeping this guy because he ends up being a discard very often. He is good as a secondary attacker vs Giratina if you don't draw into the Hex Maniac, and doing 60 for 1 Strong Energy can get you some funny donks, but it's hard to justify having him around a lot of the time.
Scorched Earth & Shrine of Memories: The old build used Silent Lab because it ran so slow that betting on drawing into / discarding the Hex Maniac vs Giratina was unreliable, but this new build is much better for that thanks to aggressive drawing with Shaymin and Scorched Earth. Scorched Earth also gets energies into the discard for Carbink and Mega Turbo to accelerate, so I feel that it makes for the best stadium to run in the deck, and 1 Shrine of Memories is always great for dealing with small things without discarding a stadium.
Cards to consider in the deck:
Regirock promo - He's not as great as he used to be due to losing Focus Sash, but he can still do the job he was supposed to - return stadiums or deal with Safeguard-type Pokemon.
Regirock AOR - OHKOs virtually any fighting-weak Pokemon, such as Darkrai-EX and even M-Audino-EX for just 3 energies, while only giving 1 prize, so if these cards are common in your area's meta, consider this guy.
Weakness Policy - P-Groudon has always been very weak against Vespiquen and that's gotten even worse as our big boy now also gets OHKOed by Yanmega if he's got a tool attached, which he probably will be as evolving without a Spirit Link in this deck is a really big setback. So this card definitely warrants consideration. It also makes Zygarde a good chunk better.
Assault Vest - A majority of the big decks use special energies so this card is still as useful as it used to be. Giratina now has to hit P-Groudon and Zygarde (if he heals once) 4 times to KO them, and this could buy Carbink an extra turn to accelerate energy.
What do you guys think? Any ideas on how to improve this build?
