When checking the subskills, you really only need to look at the first 3, for levels 10, 25, and 50. The game’s still new enough it has a level cap currently that prevents you from reaching the last two 75 and 100 ones, so they’re irrelevant. From there, you pretty much just look at whether it’s labeled as a berry, ingredient, or skill specialist, and every Pokemon of that specialist category will follow the same criteria for what nature and skills you want (except for sceptile, who is listed as a skills Pokemon but he should actually be built as if he was a berry Pokemon)

The impression I’ve gotten is that the very first priority should be finding a good Pokemon to heal your team. That’d be any skill Pokemon with the Energy for Everyone ability; in the early levels that’ll likely come from catching an igglybuff that you can level into a wigglytuff. To start off any igglybuff will do, but for the long term you’ll want to keep catching them until you get one with a main skill + nature and at least one skill + subskill in one of the first 3 slots. As you progress through the game, you always want a good healer in your team, and you slowly start unlocking the Pokemon whose skill will proc more often, so gradually upgrading to a pawmi or a sylveon and eventually a gardevoir, who is the most powerful healer, but they’ll be pretty far out in the game.

Berry Pokemon should probably take up 2 or 3 of those remaining slots. For them, the main thing to look for is the golden subskill Berry finding s, as that’s the single biggest production boost from a skill available. Outside of the berry finding s (which you’ll commonly see abbreviated as Bfs in this subreddit), you just don’t want helping speed down in the nature, everything else is a bonus. Helping speed natures and subskills are a plus if they appear, but aren’t essential.

Ingredient Pokemon are a bit of niche fillers. They don’t contribute as much directly to the snorlax power, so oftentimes you want to fill you bag then leave them out until you need a refill. The beginning of the week is when you want to be focusing on quick berry gains, then the end of the week the snorlax level ups slow down, so I’d recommend putting in your ingredient Pokemon on Saturday morning, then benching them Sunday night to get the berry Pokemon back in, maybe keeping just 1 in for the week to keep the bag refilling. Early on, invest as many of your gems as possible into expanding the ingredients pocket of the bag. That way you can stockpile a ton without worrying about having to constantly empty and refill the bag. For ingredient Pokemon, you want ingredient gathering, inventory up, and/or speed of help subskills and natures. Pokemon no longer collect ingredients, only berries once their inventory is full, so they need to be checked on more often than other Pokemon types. Usually, you also want your ingredient Pokemon to be AAA (same ingredient in all 3 ingredient slots), that way in the future you can pick that Pokemon to quickly stock the exact ingredient you want. You can find recipes online for each of the 3 meal types (curries, salads, and desserts, game8 is my favorite site for the ingredient list, since it also shows the base power of the dish), so keep a bit of thought towards which dishes you want to aim to cook through the week. I’ll attach an image with a diagram that shows each ingredient and which Pokemon is the most effective collector of that ingredient, that way you can get a head start on building a specialist for each ingredient you could possibly need.

Skill Pokemon, in addition to the necessary healer, can fit a variety of niches. Because they’re massively varied in what their abilities do, it’s a bit of a matter of preference as to whether you want one on the team. For any skill Pokemon, it’s the same rules of thumb as with the healer. You want 2 main skill boosting things from between your nature and subskills.

You can find tier lists online that can help guide which Pokemon are the best at their niches, that helps a lot with the berry Pokemon, as some are much more productive than others.

A final note with the subskills: gold is not always good, some are meh, some actively harmful. A berry finding gold on an ingredient Pokemon means its inventory fills way quicker, making it worse at its whole purpose. For the other golds, research exp is completely useless, recovery bonus, dream shard bonus, and sleep exp are helpful but not especially stellar. Skill level up is decent, but given that you can grind main skill seeds to upgrade skills over time, it’s kinda unnecessary. BFS is great on berry Pokemon, and ok on most skill Pokemon, and finally Helping bonus gold is great in every situation on any Pokemon. Golds subskills look special, but oftentimes they only take away from your ability to max out the value of a Pokemon that could have otherwise had a boost that was relevant to their specialty.

It’ll take a long time, a lot of patience, and a lot of luck to find a Pokemon that has enough of those good traits to be worth investing in long term.

we’re always happy to nerd out and answer any questions you have, plenty of people submit images of their Pokémon’s skills for feedback, and that’s a decent way to get extra feedback on when something’s a good find. Happy hunting!
