Oh ok, thats a pretty nice start!
So, you should probably start off with something like this:
3 Darkrai
3 mewtwo
2 Sableye
8
4 Juniper
4 N
2 or 3 random reciever
2 Bianca
4 Dark Patch
4 Energy Switch
4 Catcher
2 Eviolite
2 Tool Scrapper
1 Computer Search
4 Ultra Ball
33 or 34 (Matter how many RR)
9 Dark
4 DCE
13
thats 54 or 55 cards, so you need 5 or 6 more,
That could be 1 switch or Keldeo EX, another dark, a max potion/potion, Skyla if you want, Bouffalant, another eviolite, a super rod, pluspower, etc
I would recommend a switch/Keldeo EX, super rod, dark, eviolite, and something else.
Hope I helped.
