>>24836162In TPDP, here's what you have to do.
Take your chosen puppet. Reincarnate it (aka press a button and done) using the rainbow stone until it has flawless IVs (assuming both "parents" are perfect in terms of IVs, it's a 1/16 chance to get perfect IVs everywhere; getting the first perfect puppet will still be difficult but once you have that things will get infinitely easier), using whatever mark you want to ensure it has the right boosted stat.
Now level it up and stance change it to whichever stance you want. Use your PP to put the EVs exactly where you want them, and then if it has the wrong ability spend the 20 PP to switch it over to the other one.
(Note that there's an item that does this in Pokemon, but it doesn't work for hidden abilities and costs 200 BP, which is best described as "more than a full party's worth of top-end hold items". I ran out of space last post to mention how many hours of Battle Maison you'll have to go through in order to get the items you need, and how since hold items can't be ported over across generations anymore you'll have to repeat the grind again in a few years anyways.)
Also note that in TPDP said top-end hold items cost regular money. Lots of it, but there are easy sources of money to grind on and it takes nowhere near as much time to afford even a 250k item as it does to afford a 48BP item in Pokemon. And since item clause is enforced online under normal circumstances in TPDP, you won't need more than one of a given item.
Now level the puppet up to 70 (which is when it learns it's last move from leveling up), use PP and skill cards to finish the moveset up, give it whatever item you want it to use, and you're done with that puppet. And if you know what you're doing you can do this with up to 5 puppets at a time as long as the last one can 1-shot anything you have it fight (whereas in Pokemon you have to wait until you've finished EV training first).
The only agonizing part is finding a battle online.
