Only cards from Majestic Dawn, Legends Awakened, Stormfront, and Platinum are allowed. However, Energy from previous sets are also allowed.
x4 Stunky (Stormfront)-A 60 HP basic with Psychic resistance that can do 40 damage for two energy. Needed for evolution.
x3 Skuntank (Stormfront)-100 HP and resistance to Psychic. Evolutionary Gas is nice as it allows me to have a turn in which the opponent can't damage me. Plunder is a decent three for 60 that discards all Trainers attached to the Defending Pokemon.
x3 Poochyena (Platinum)-Can get me more Poochyena and also can do 20 damage for one energy. Also has Psychic resistance. Needed for evolution.
x2 Mightyena (Platinum)-Collude is a decent attack. It is a two for 40 if I played a Supporter card that turn. And Desperate attack can be a three for 80 if I have less energy attached to Mightyena than the Defending Pokemon, which is pretty easy to do with Cold Feet, which if Mightyena is affected by a Special Condition makes all Mightyena's attacks cost zero energy. Mightyena also has Psychic resistance and no retreat cost.
x2 Skorupi (Stormfront)-A 60 HP basic. Needed for evolution.
x2 Drapion (Stormfront)-110 HP. Scorpion Grapple is a great, a zero for 10 that either paralyzes the foe or prevents them from retreating. Cross Poison can do 80 damage for two energy and poisons about half the time. Derail is nice, a three for 60 that discards all Special Energy attached to the Defending Pokemon, making it great especially against Steel and Dark decks.
x4 Darkrai (MD)-An 80 HP basic with Psychic resistance. When I play it I get to put the Defending Pokemon to sleep. Dark Slumber is a decent one for 10 that will put the foe to sleep. While it isn't an instant sleep, this is better as it allows Dark Resolve, a three for 40 that removes four damage counters from Darkrai if the Defending Pokemon is asleep, to be more likely to activate its effect.
x1 Skuntank G (Platinum)-An 80 HP basic that hits for Psychic weakness. Smokescreen is a decent two for 20 that can stop my foe from attacking. The main point of this card in this deck is Poison Structure, which not only can Poison the Defending Pokemon but also Poison my Active Pokemon, which means this helps out Mightyena.
x4 Buck's Training (LA)-Drawing and a Pluspower effect.
x4 Marley's Request (Stormfront)-An Item Finder.
x4 Potion (Stormfront)-Healing.
x3 Super Scoop Up (MD)-Can bring Pokemon back into my hand with all their cards attached also brought into my hand. This can help to psuedo-heal damaged Pokemon but also to allow me to activate the abilities of Darkrai and Skuntank again.
x2 Poke Drawer + (Stormfront)-Drawing and getting me cards.
x1 Snowpoint Temple (LA)-Increases the HP of basics and removes any Stadiums my opponent might have in play. Mainly there to allow Skuntank G to use Poison Structure.
x17 Dark Energy-Needed.
x4 Darkness Energy (Neo Genesis)-Provides energy while also making my Pokemon do more damage.
