BW-on Darkrai-Hydreigon deck help.

[Master_Z]

I'll likely run this at a Battle Roads this weekend, so any advice would be appreciated. It's a pretty standard list aside from a few cards. I chose Mewtwo Ex over Sigilph because it's a more versatile card. I wanted 3 Sableye, but it wasn't doable after I added in the third max potion and 2 tool scrapper, both of which are necessary. I'm also debating about adding Cheren in for consistency.

Pokemon (14)
3 Deino (dark type)
1 Zweilous (dark)
3 Hydreigon (ability)
3 Darkrai Ex
2 Sableye
1 Mewtwo Ex
1 Shaymin

Items/Supporters (34)
4 Juniper
4 N
2 Bianca
2 Random Receiver
4 Catcher
3 Ultra Ball
2 Level ball
2 Eviolite
3 Max Potion
2 Tool Scrapper
3 Dark Patch
3 Rare Candy

Energy (12)
8 basic Dark
4 Blend GRPD

I had a list very similair to this one for a while but it wasnt working too well. Mostly everything is fine but the level doesnt have much of a point in the deck anymore. the reason a lot of darkrai decks play level ball is not only too search out deinos and sablyes but to also search out the teched siglyph. But mewtwo is a better tech in my opinion. So i would suggest to drop the 2 level ball for a 4th ultra, which will help you open it more consistantly to potentially set up t2 darkrai attack using dark patch, and a 3rd sablye.
