Night March is actually an Expanded deck, but it's the most amazing deck I've ever had the pleasure to play xd It's pretty much the only thing I play nowadays, but I honestly never get tired of it. I'll give you my list so that you can take a look at it.

The idea behind this deck is to stack damage really fast. If you're familiar with the more recent Lost March, this is similar but it stacks with Pokemon in your discard pile. There are 3 cards in this game with the attack "Night March", and you can use a maximum of 4 copies of each (as it is with any other card), so you can have a total of 12 cards with the attack "Night March" in your deck.
Night March does 20 damage for each Pokemon in your discard pile that has the attack "Night March", meaning that if you discard 9 out of the 12 NM cards you're already in the 180 damage range, which OHKOs most Pokemon EX and a lot of Basic Pokemon GX. Because you have a good type advantage coverage (Electric with Joltik, Psychic with Pumpkaboo and Mew, Fighting with Marshadow-GX), discarding as few as 5 NM cards is enough for a OHKO against a lot of popular decks. Discarding with this deck is also very easy because you run 4 Battle Compressors and 4 Ultra Balls. Using Ultra Ball to discard what remains of your hand, dropping a Shaymin-EX to draw up to 6 cards (without using any Supporter cards yet), and then discarding again with Professor Sycamore means that you can almost always reliably score a KO on your first turn.
Speaking of which, this deck makes the start of the match coin flip a win-win scenario for you. If you win the coin flip, you make your opponent go first. If you lose it, most people will chose to go first anyways. Because of how easily you can KO anything in your first turn, you always want to go second to attack right away and take the lead in the prize race.
The main advantage of this deck is that it easily OHKOs Pokemon EX and GX without having to use EX or GX attackers itself (you have Marshadow-GX, but I typically don't attack with it unless I need the Fighting type weakness), which means that more often than not you'll be ahead in prizes.
The deck is rather cheap too compared to other popular decks Like Buzzwhole-GX. The only expensive cards in this list are the Tapu Lele-GX (which I don't use that often here anyways) and the Computer Search (which is very nice but you can definitely forego without hurting the deck too much). Shaymin-EX are worth like 2 packs each, Marshadow-GX costs around 1 pack and everything else costs 1 pack or less. The NM cards themselves cost very little.
Personally I think it's fun to watch that little demonic spider with only 30 HP take out 200+ HP Behemoths like M Rayquaza-EX in a single hit in your first turn and using a single energy xd It's not as OP as that sounds though, there are some tech cards that anyone can use that can counter it pretty hard such as Oricorio (I run one in this deck myself for easy wins in the mirror match), and then there's Trevenant which is an auto-loss most of the times. But that aside, it's incredibly consistent. It's strong against a wide variety of decks and I rarely draw dead with it because of how many consistency cards it runs.
If you're interested I can showcase the deck a little for you when you catch me online. If it looks like something that you might want to try, I'll be happy to help you build one.
Now, for the time being it might be faster to start by getting a solid Theme Deck and using that. From the list you have there, Hydro Fury is something I can recommend for a starter. It's pretty good and it has type advantage against Blazing Volcano, which people are playing a lot in the Theme format. It's definitely not an auto-win against Blazing Volcano, but it's pretty strong. I think Mach Strike is still pretty good, although it has fallen out of favor a little.
Crushing Current has seen better days, that's for sure. At some point it was at the top of the Theme Deck food chain, but it was a little too dominant and it got nerfed in the end (online exclusive decks can be subject to nerfs and buffs; the regular Theme Decks that you can buy in stores and redeem for 500 tokens will always stay the same). I haven't seen anyone use it in VS for while. Hydro Fury, Mach Strike and Blazing Volcano (if you feel like buying it for another 500 tokens) are good places to start.
EDIT: Can we request to move this to the Deck Construction forum maybe (if Orig is ok with that)? This thread has become more about deckbuilding than anything so I think it would fit better in that section now.
