combo

Deck more reliable and less tied to counterpart luck with LickilickyEX. More defensive.

Dialga in front, 2 energy as soon as possible, Giant Cape to help tank the first 3/4 turns.
Give the energies to whoever is on the bench, possibly Meltan -> Melmetal.
Melmetal should be managed with RockyHelmet and keeping potions for him.
Blows of 120+RockyHelmet are enough to knock down just about anything.

Very simple and fast deck. 
If you can get Manaphy and Vaporeon turn 2 you can already attack with Palkia for 150 damage.
You tend to turn 3 almost always attack with Palkia.

Plain and simple.
Druddigon in front with helmet to stall. 
Only water and lightning energies. 
A Dawn to make unexpected comebacks.
A Pokemon Communication to help that once in a while.

Very balanced deck that requires you to always believe in it. With Dragonite you could be down 0-2 and come back to 3-2 in 1 turn. It is much quicker to build up than it looks. 

If you go first: Attempt to get get a combo of Pachirisu Ex + Magneton + Dawn + Tool going. This will allow you to attack for 80 on your 2nd turn and likely KO any basic Pokemon the opponent put into play. If Magnemite is forced to come out but you are able to draw into the rest of the combo plus you have an X Speed on hand, use that X Speed before evolving into Magneton.

Great at one shotting Ex Cards with Mesprit.

Use Azelf and Cyrus to take out who you want.

Get the trio quickly using Oak, Balls, Slabs and Comms.

Ideally Uxie out first to generate energy on benched Mesprit.

Mew is good if you need to tank some damage, and in some cases its worth building up genome hacking.

Use X Speeds as needed to swap out mon. Works well with Dawn for a surprise attack with Mesprit.

Keep your copies of the trio in you hand, so opponent thinks their safe from your Mesprit when they K.O one of your trio.

Double energy: Water + dark

• damage backrow with Greninja
• swap with Cyrus
• stall with Arbok

Going second, try to get Meltan in there to get some free energy, then get out with an X speed, evolve, and wreck. 

Going first, try to rely on Mawile to knock off energy from your opponent. 

2 Potions and Blue are uncommon choices, but I think they both pair well with Melmetal's ability. Blue in particular gets melmetal to 160 effective HP, which was very helpful during the Celebi metagame we just went through. 

Archiving this deck here, as I will of course be changing it with the new steel types like Dialga EX. 

Druddigon or Kangaskhan for early tanking while you load energy onto Darkrai.
Use Magneton's Volt Charge to gain Electric energy before evolving to Magnezone.


If you have two Darkrai's you can even use Dawn to get 40 Damage before you use an attack by putting your energy to the benched darkrai and then get dawn to move one energy to the darkrai on the active spot.
