Only cards from Diamond and Pearl, Mysterious Treasures, Secret Wonders, and Great Encounters are allowed. However, Energy cards from previous sets are also allowed.
x3 Snover (MT)-A 60 HP basic that hits for Grass weakness. Also has a zero energy attack that lets me look at my opponent's hand. Needed for evolution.
x2 Abomasnow (MT)-100 HP and hits for Grass weakness. Its Fire weakness can be covered by the Water types of the deck. Glacier Snow puts foes that attacks Abomasnow to sleep, which is nice (or should I say... ice. :3) Heavy Blizzard is a really good attack, a three for 60 that can put one damage counter on each of my opponent's benched Pokemon.
x3 Magikarp (MT)-Flail can do 20 damage for one energy and Dragon Rage can do 60 damage for two energy. Needed for evolution.
x2 Gyarados (MT)-120 HP and Fighting resistance. Dragon DNA is great, seeing as this means I get the coveted Flail. And this Flail gets a nice boost from Dragon DNA, making it able to do up to 140 damage. I can also use a risky Dragon Rage for a chance at 90 damage. Enrage is amazing. A four for 80 that has me flip coins until I get tails and then I get to discard a card from my opponent's hand for each heads. Gyarados is just incredible.
x3 Wailmer (GE)-A 90 HP basic that has a two for 10 attack that can do 10 damage to each of my opponent's benched Pokemon. Needed for evolution.
x2 Wailord (GE)-200 HP!!! And it has a four for 60 that puts it to sleep. And when it is asleep it heals off damage. And combine that with Leftovers... Wailord is never going down is it?
x2 Piplup (D&P)-A 60 HP basic with a zero for 10 attack. Needed for evolution.
x1 Prinplup (D&P)-For one energy it can do 10 damage to each of my opponent's Pokemon. It can then do for two energy 40 damage to a Pokemon with damage counters on it. A solid Pokemon.
x2 Lapras (GE)-An 80 HP basic. Being able to put a Supporter, a Pokemon Tool, and an energy into my hand from my deck is pretty great.
x4 Warp Point (D&P)-A Switch and Gust of Wind in one card.
x4 Potion (D&P)-Healing.
x4 Leftovers (GE)-Healing.
x3 Roseanne's Research (SW)-Gets me Pokemon and Energy.
x3 Team Galactic's Mars (SW)-Drawing and puts a card in my opponent's hand to the bottom of their deck.
x2 Rival (D&P)-Gets me cards.
x20 Water Energy-Healing.
