It’s about a pretty new deck that should be seen at some Cities. As you may have realized because of the title, it’s the Gliscor-Spiritomb Lock. The main strategy of this deck is to paralyze your opponent’s active Pokémon with Gliscor LV.X’s Poké-Power “Shoot Poison” and return it to your hand with the regular Gliscor’s “Burning Poison” attack to do it again and again. You may think you won’t do any actual damage by doing this, but the paralyzing special condition comes along with Poison and “Burning Poison” can Burn your opponent’s active Pokémon.
There are two things that definitely hurt this deck, first being TGI Power Spray or any Power-lock in general. Secondly, Unown G or basically anything that can avoid Special Conditions (Xatu SW, Recover Energy GE). There are some other cards which can be awful for Gliscor/Spiritomb players too; I’m talking about field manipulation cards which either switch out your opponent’s active Pokémon or yours. Cyclone Energy or Warp Energy are two really good examples, there’s nothing you can do against them (except if you tech in Empoleon SF, but it’d be rather slow), so beware of them.
The only thing that comes into my mind what could defeat this is Scizor MD. It hits for 80 damage against Pokémon with any Special Energies attached for just one Metal Energy. Besides that it does really well against one of this decks worst matchups: Plox! They play many Special Energy cards like Call or Upper Energy, plus Scizor has Psychic resistance which is pretty good against Gardevoir because of her already low damage output.
Other annoying cards for Gliscor are Warp Point and Switch, but that’s were this decks techs hit the floor. Spiritomb from the brand new set Platinum: Arceus prevents both players from playing normal Trainer cards, like Switch and Warp Point. Spiritomb’s “Darkness Grace” attack also can help you setup, but he’s mainly there for “Keystone Seal”.
Another nice tech for Gliscor decks are either Palkia LV.X from Great Encounters or Luxray GL LV.X from Rising Rivals. Both have the ability to pull in one of your opponent’s benched Pokémon. Also both have their own advantage; while Palkia LV.X can’t be Power Sprayed, Luxray GL LV.X can dish out a fair amount of damage for low cost. This is just personal preference, but I like Palkia LV.X better because it can’t be Sprayed which is really good in case you need to pull in something weak for a prize or even your final prize.
This deck has some good matchups along with a few bad ones. For example against decks like Venusaur, which can’t even be effected by Special Conditions, you’ll fail badly. Also, with really fast decks like SP-Toolbox / Variants, Kingdra, or Gyarados you may have problems, but it depends all on your techs. If you have a Mr.Mime MT in your hand you can easily stall around against them since they don’t need much energy to attack. All in all this is a pretty decent deck and it should do well at some cities.
[Editor’s Note: Just in case it is unclear, the combo is that you send Spiritomb out after returning Gliscor to you hand, which prevents your opponent from removing the Paralyze special condition with a card like Switch or Warp Point. You then retreat Spiritomb (for free if you have an Unown Q attached) and Level Up a second Gliscor that was on your Bench from last turn to repeat the process. Your opponent will never be able to attack unless they evolve or play a Cyclone or Warp Energy.]
