Sorry this took me so long to reply, I've been busy. :/ Well, I scrapped Zebstrika/Garbodor and built a Hydreigon based deck with Darkrai EX, Terrakion EPO, and Keldeo EX. Terrakion can OHKO anything weak to it or having less than 110 HP, and with 2 out and a Hydreigon you can chain Sacred Swords until you don't need to anymore. EDIT: Just saw your post, so all I need is a Keldeo and one Terrakion plus Darkrai for Keldeo's retreat. Keldeo EX is for Rush In, but it can also be a useful attacker if you have 3-4 Prism in play. Darkrai EX provides free retreat and also is helpful in setting up KOs for Hydreigon, whose attacks add up to 170 with snipe damage which is just enough to take out Thundurus EX, Deoxys EX, and Keldeo EX. It misses the knockout on Darkrai and such, but at that point a Deino could take care of it. Most of the time you'll be using the Darkrais or Terrakions for them anyway. Hopefully, that's going to work out.
On a different note, it snowed at least 4 inches this morning. MAY 2ND. SNOW GET THE HECK OUT OF HERE SGASKGSFHPHJR
