Buddy, level x's count as the form below it in deckbuilding. So the max line you can have is 2-2 (the best line to use). You don't need 4 lost worlds, 2 is normal, 3 is the most (and sometimes that is overload). Pokemon Rescue is pointless in this deck, along with having 4 unown q's, 2 dittos (why??), 2 moomoo milks, and 4 Smeargles (2-3 with sableye is so much better). Also, since SP is going to be played, why would you wanna boost there HP with snowpoint along with yours, making that card not the best. You're only playing 2 x's, and with other search (which sould be here!!!) 2 premier balls is the most you'll need. Recovery cards such as aaron's would be a ton better than rescue is this deck too. The Seekers is OK, though i'd rather play something else, and you're using SP, so poketurn over scoop up. Lemme give you a list that is going to be a lot better than this (no offense) and a little explination on why I'm using certain cards.
2-2 absol g x (main attacker, you know this)
2-2 garchomp c x (sniping, healing, backup, can donk in some situations)
2-1 uxie x (draw/machamp counter)
2 Smeargle/Sableye (starter-you can choose which one)
1-1 BDK (Honchkrow SV: the gyarados/machamp counter. a legitimate beast)
1 unown q (free retreat for smeargle or sableye)
1 azelf (for searching in the prizes)
1 chatot g (i see that you're goal is to get pokemon in the lost zone, so put pokemon on top for the flips)
2 crobat g (extra damage)
1 honchkrow g (sniping and can search out SP trainers/lost zone)
Total: 21
T/S/S
4 cyrus (your search engine basically)
4 poketurns (i don't know why you weren't using these before, so much better than SSU)
3 gains (self explanitory really)
3 sprays (again, self explaintory)
3 SP radar's (searches out your SP's. any of them, even x's. Better than premeir ball in every way)
2 aaron's (recovery, better than rescue in every way)
3 pokemon collectors (self explanitory, and you really only need 3)
2 bebe's (more search, can be dropped)
1 lost world (tech really, you can win both ways, and you'll knock out pokemon more than LZ them)
1 twins (recovery card really)
Total: 26
energy
3 DCE
3 call
3 sp. dark
4 regular dark
Total: 13
This list should run much more efficiently than your old one. Your LostGar matchup will be practically an autowin, your VileGar being an easy match too. As of LuxChomp, you may wanna fit in a 1-1 umbreon to help, though if you take out there garchomps before you lose yours, than it'll be close. SableLock actually looks a lot like this, but they run draggy FB, so again, make sure your chomp doesn't die. Gyarados and Machamp will be extremely hard matchups, even with BDK and Uxie X. This is a matchup if you can win lost zone, do it.
