For your later reference, I suppose, I have edited both your list and your strategy.
My SP lists tend to be controversial, so I've tried to be conservative here, but once you get good enough to really tweak the list and know what you're doing, you will understand why.
===========================
2-2 Garchomp C Lv.X good
2-2 Luxray GL Lv.X good
[del]4 Sableye SF[/del] Luxchomp focuses on SP Pokemon, speed is paramount
2 Uxie +1 Lv. X - I strongly recommend playing the Lv. X in here, it is VERY helpful
1 Azelf
[del]1 Chatot G[/del] unnecessary
[del]4 Unown Q[/del] You only need one
1 Unown Q
1 Promo Toxicroak G
1 Dragonite FB/Ambipom G
1 Bronzong G the primary purpose of Unown Q and Bronzong G is to help you control your field; Unown Q allows you to have another Pokemon with free retreat (usually Uxie Lv. X) and help you better control who is active, and Bronzong G lets you move energy around so you can better control what attacks. With a deck that moves as quickly as Luxchomp (and needs as much energy), that energy movement is VITAL. Dragonite/Ambipom and Toxicroak are used for knocking out opposing Garchomp Cs and Luxray GLs, respectively, which is VERY important as well.
Luxchomp's trainer line is critical to its success, you have to understand the workings and purpose of every one of your trainers - you can get away with half-heartedly throwing in energy and even pokemon, but trainers are game breakers
[del]4[/del] 1 Bebe's Search you only need one, maybe two at most.
4 Pokemon Collector good, 3 is popular too
[del]4 Seeker[/del] Totally unnecessary when you have Poke-Turn instead
[del]1 Copycat[/del] Not that this is necessarily a bad play, PONT is preferred, but I am being conservative
[del]3 E-Belt[/del] If you play Belt you would probably only play one or two, but that's not so common as far as I am aware
1 Luxury Ball good
[del]4[/del] 1 Communication I think 1 is standard now?
[del]3[/del] 1 Premier Ball Yes, you run lots of Pokemon Lv. X, but you don't need THAT much...
[del]1 Level Max [/del] I know it's hard to believe but this is actually a bad card
4 Poke Turn
3 Power Spray
3 SP Radar
3 Energy Gain
4 Cyrus' Conspiracy
1 Aaron's Collection Do NOT underestimate the power of the SP Trainer set. Without it, Luxchomp is absolutely useless. There are all of these cards meant to for use with SP Pokemon - USE THEM. Don't even bother with the deck unless you have all of these.
4 DCE good
[del]4[/del] 2 :lightning: Energy one or two at most
[del]3 Rescue Energy[/del] good card yes, good play probably not - Luxchomp does not have this kind of room
1 Psychic Energy Promocroak needs it, Azelf can attack with it but that's worst case scenario
4 Call Energy So helpful. So helpful in everything that uses Colorless energy. All the time.
Strategy: It's a basic Luxchomp deck strategy.
And this is what Luxchomp's strategy is.
You start out the game as blazingly, explosively fast as possible. Don't worry about setup. Don't worry about getting your Lv. Xs out. That will all come in time. From your very first turn, you should be scanning the field, hunting for the weak and vulnerable so you can knock them out immediately. Luxchomp thrives on first and second turn knockouts, using its insane speed to put the opponent at a disadvantage from the beginning.
Once you've tilted the board you can "worry about setup" a little more. But your primary focus in the entire game should be grabbing the cards you need to make that next knockout, every turn. If you can't take a prize at LEAST every other turn with Luxchomp, you're either facing a masterfully played anti-SP deck, or you are running the deck wrong.
Oh. Also. Don't underestimate the amazingness of Power Spray. Most decks thrive on early game Uxies, and spraying opposing Galactic Switches, Level Downs, Set Ups, Bright Looks, etc. can turn the game around.
Please note that this list has about 6-7 open spaces. Those are spaces that are really down to what your own style is, what cards your ability dictates you should run. Mewtwo or Machamp counters? Additional SP support? Mirror advantages such as Twins or Cynthia's Feelings? It's all up to you bro.
=================
I wanted to add that I was once in the same position as you. I was testing some decks for CCs last year, and I decided to throw together Blazeray to test against because I happened to have the cards for it, and I had heard it was popular. I all but netdecked a list, basically - added in some weird stuff like Weavile G - and played it against my own deck a few times. It took me about three games to go "...Wait, holy crap, this WORKS. Really, really well. This is ridiculous, why haven't I been playing this the whole time?"
Been a decently competitive player ever since then, that was kind of a turning point.
