Only cards from Majestic Dawn, Legends Awakened, Stormfront, and Platinum are allowed. However, Energy from previous sets are also allowed.
x3 Horsea (LA)-Needed for evolution.
x3 Seadra (LA)-Has a powerful one for 30 that allows me to discard up to two energy in my hand and has this attack do 10 more damage for each energy discarded. This allows it to be a one for 50 and provides great set up for Kingdra. Needed for evolution.
x2 Kingdra (LA)-An excellent card. 130 HP. Aqua Stream is an excellent zero energy attack. I can search my discard pile for as many Water energy as I want, do 10 damage times that amount of energy, then put them back into my deck. This keeps me protected from decking, from energy removal, and works great with Seadra and Kyogre. It also works well with Kingdra's Dragon Pump. This attack works really well in this deck. It is normally a one for 40, which is very good already. But if I discard two cards from my hand this causes Dragon Pump to become a one for 60 that does 20 damage to one of my opponent's benched Pokemon, for a total of 80 damage. This makes Aqua Stream more powerful and puts Magikarp in my discard pile without having my opponent gain a prize.
x4 Magikarp (Stormfront)-Well, if it gets forced out there at least I have a zero energy attack that has me flip a coin until I get tails and then draw a card for each heads. Needed for evolution and making Gyarados incredible.
x1 Gyarados (Stormfront)-This is an incredible card. 130 HP and resistance to Fighting. Tail Revenge is an excellent attack. It does 30 damage times the number of Magikarp in my discard pile, for no energy. This means with help from Kingdra it can easily end up being a zero for 90! Wreak Havoc is another incredible attack. It is a two for 40 that has me flip a coin until I get tails and then discards the top card of my opponent's deck for each heads I get. So I can potentially deck my opponent and win on turn three. Then we have the third and final incredible attack. Dragon Beat might require five energy, but with Kyogre and Manaphy this is easily achieved. It is a five for 100 that can discard one energy attached to all my opponent's Pokemon. This card is just incredible.
x2 Eevee (Lv. 12) (MD)-60 HP and a zero for 10 attack. Needed for evolution.
x1 Vaporeon (MD)-Cleanse Away is a great one for 30 that removes two damage counters from each of my benched Pokemon. This combined with the healing of Dawn Stadium make my Pokemon almost impossible to take down. Hyper Whirlpool is a great attack. A three for 60 that has me flip coins until I get tails and then discards an energy attached to the Defending Pokemon for each heads.
x4 Kyogre (LA)-A 100 HP basic. Drizzle works very well with Dawn Stadium and just is a great attack in general, a zero energy attack that has me attach two energy from my hand to one of my Pokemon. High Tide works incredibly well with KIngdra. It is a three for 60 that has me discard two energy attached to Kyogre. Then it does 20 damage to each of my opponent's benched Pokemon. Kingdra can then use Aqua Stream to recover the energy discarded and do more damage.
x4 Manaphy (MD)-A 70 HP basic. Aqua Skin works great with Dawn Stadium, as this means that whenever I attach an energy to Manaphy I get to remove three damage counters from it. Chase Up is a nice attack to get me any card I need. Fountain also works well with Dawn Stadium and also with high energy cards like Gyarados. It is a two for 30 that has me attach two energy in any way I like to my benched Pokemon.
x4 Buck's Training (LA)-Drawing and a Pluspower effect.
x4 Marley's Request (Stormfront)-An Item Finder.
x4 Pokemon Rescue (Platinum)-FOr if I don't have any Magikarp or Energy for Kingdra to discard, I can discard another Pokemon and use this to get it back. It can also be nice to get back Manaphy or Kyogre that I might lose. I can also use this card as protection against the event that the Magikarp that I would use to evolve into Gyarados is taken down by a bench damaging attack.
x1 Dawn Stadium (MD)-Heals my Pokemon and removes any Special Conditions they have.
x23 Water Energy-Needed.
