Looking for advice. I pulled a breakdancing genesect v from a fusion strike pack, and I'm using the packs I got for it to make a budget semi viable deck. I already have 2 Victini Vs and 1 vmax, so I'm going for a consistent engine deck or something. I have all relevant theme decks, and regularly participate in tourneys. 20 Lost Origin packs to my name, anything I should be doing?
Unfortunately Victini is struggling to say the least right now. So far in Lost Origin, limitless has recorded that across 93 tournaments in the format consisting of 18513 matches, there has not been one Victini vmax deck played. Victini is weak to water when the BDIF is palkia intellion, and a lot of decks are playing thick lines of Intellion SwSh and attack with it. Now you also have cramorant thrown in as a water type attacker in the most played deck. Plus one prize decks are at their peak and victini can't ohko common one prizers like Regis.
If you absolutely must build a victini vmax deck, the deck engine is going to be simple at least. Magma basin takes care of energy attachments for you, and you're going to want to run heavy heavy boss counts (4 boss, 4 pokegear at least) to tempo out the opponent and KO their evolving Vs before they can evolve. You can also throw in some Roxanne and a radiant charizard to put them at a low handsize and then shove a strong one prizer in their face after they KO a vmax.
Moving on from Victini, you are in luck - one prize decks have not been this strong in a long long time. I would highly reccomend looking into the lost box deck - not only is it strong and inexpensive, but the deck engine is worth investing in. It should be in format for a long time and can be easily adapted to fit future decks and archetypes. Even now, you can use lost engine with one prize box, giratina Vstar, dragonite V, Goodra Vstar, Vikavolt V, and Dialga vstar.
Right now there are two general builds of lost box, mainly centering around cramorant focused builds that use mirage gate and snorlax because snorlax + cramorant's damage hits perfect numbers for Vstars. These decks usually play greninja as your radiant pokemon, whichis the cheaper radiant. The other build focuses on heavy sableye, this is advantaged vs opposing one prize decks but plays radiant charizard which may be a bit much for your budget.
here is Alex Schemanske's take on the sableye version of the deck he used to get 1st in a 433 player tournament two days ago:

here is a video from Omnipoke on a cram/snorlax focused build that also just talks about the engine in general - good video to watch to understand the basics of the engine:
Finally, if you want an alternate budget deck, Regis is still very strong in format and got a massive upgrade with lost origin thanks to gift energy which fits the deck perfectly. Here is tablemon, the highest placing regi player at worlds playing the deck:
Don't fall into the trap of using gimmicks like Thorton is Regis - while it can lead to crazy youtube highlights, its very inconsistent and usually just leads to bricky hands and Regis is strong enough as it. 2 Gift energy is all you really need.
Finally, if you aren't opposed to being hated by a lot of the people you play against, it might be worth watching the control space - aka Sander Wojcok's twitter. No one has put anything together yet (at least not publicly) but control has all the tools needed to break out as a budget deck in a big way. Whether as Eldegoss using it's attack to forever loop itself and play Fantina every turn to never die and deck your opponent, or something like the below to trap an opponent and use Miss Fortune sisters, perrserker, and chandelure to mill all their switching cards
