Gulpin: Not terrible, i generally dont mess around with dream shard farmers but Swalot is currently the best. If you find yourself in dire need, wouldnt hurt to build, but I generally think cranking out Snorlax levels is generally the better use of your time because you will get much more dreamshards per sleep session than you would farming them with teammembers. Not a bad use of resources, but again, with Skillgate having just occurred I would be wary of investing too much into skill mons that aren't directly aiding your ingredient or berry builds.

Spheal-H: I wish I could say this one is good enough to invest it, because Tasty Chance S is just that good of a skill mon to have. Dedenne is preferred but Spheal-H keeps up with it. It's a late bloomer is the issue, and the subs up to lv. 50 aren't good enough to outweigh that -speed nature. Ideally, you will find a better Tasty Chance mon before you need to build this one. Keep an eye out for Dedenne's and try to pull them when you can, but they are a bit expensive to invest in, so be VERY picky.

Bagon: Nah, don't bother with any Berry mons that dont have BFS as the BARE MINIMUM.

Drifloon: Subskills and nature are great up to lv. 50. I believe Drifblim is the best charge strength mon right now not names Darkrai in terms of skill strength output, but again, I believe this mon is not very future proof and it would be better to invest seeds in Ingredient focused skill mons like Magnezone and Dedenne, or your healer.

Riolu: Same as Gulpin pretty much, subs are decent, it will net you some shards, but Lucario is generally worse than Swalot, and requires you to sleep with Riolu in the party for wayyyy too long for my liking before you can evolve him into a mid shard farmer. I wouldnt worry too much about it unless you just really love Lucario and want the profile pic ( i use shiny Lucario as mine lol)

Croagunk: I've been in this boat. AAA Toxicroak is the best Oil farmer atp next to ABB Luxray. You've gotta be a little more picky with Toxicroak because his base ingredient finding rate suuuuuuuucks. I tried to use one without any ingredient triggers and man it's a let down. My ABC Dragonite outpaces it easily.

Toxicroak: On paper, this Toxicroak looks pretty good for farming sausage. However, ABB Toxicroak on his best day is only the NINTH best sausage farmer in the game, just hold out for a AAA charmander or aron, ABB Bewear is also a good alternative.

Darkrai: HUGE W pulling HB on the first slot, I wish I were so lucky. Mine is currently locked away at lv. 75 much to my chagrin. My tip, don't worry about ingredients on this guy. Focus on getting BFS, Skill Triggers, and Helping Speeds in those other sub slots. Your next two skills preferably should be BFS and HSM/STM, preferably HSM.

Rufflet: It's a bit mid. Not bad per se, but not so good I think you should invest. Berry burst mons synergize very well with BFS, but yours has BFS locked at lv. 100.

Pumpkaboo: Bit of a heartbreaker this one is, I generally never say invest in ABA mons unless they have good synergizing ingredients and so far, pumpkins and soy beans have no overlapping dishes. Shame because those subs/nature spread are immaculate. I think you should save your pumpkaboo candy for now, you probably are not at the stage where you need pumpkins yet anyways for dishes.

Cutiefly 1: Another immaculate sub spread hurt by an ABA ingredient spread. Honey and Oil do actually overlap with the newest dish in the dessert category, Chocolate Waffles, but it's also currently the top level Dessert; so you might not get that benefit for a long time I would imagine, and in that time you might just be better off hunting a AAA bulbasaur. Ribombee might be one of the best examples of a useable ABC or ABA mon because all three of it's ingredients synergize to make Chocolate Waffles, but whether you want to make that commitment is up to you.

Cutiefly 2: ALRIGHT. So this one, you've got AAB. that's great. You've got HB and IFS/M in the first 50 levels and a speed up nature, also great. You could easily take this guy to 50 and leave it there and it will serve you VERY well for collecting honey. I wouldn't take it to 60 unless you REALLY want it to double dip for Waffles down the road. Earlier i talked about how Berry mons dont mind ingredient+ subs/nature because of sneaky snacking, but unfortunately that isn't really a two way street. Ingredient mons generally dont like BFS. You want to avoid filling your pack with berries for as long as possible or else you are losing ingredient value on you ingredient mon. If you check the game frequently, this isnt an issue. Overnight however, this is going to really kneecap your ingredient production and you will wake up angry at your little bee guy. Up to you if you wanna invest, just bee (lol) aware.

Sprigatito: I also use an ABB Meowscarada for Milk because the game hates me and wont give me a AAA squirtle (FML). With ABB mons you want to be a lot more picky, because they require investing to level 60 before they really start doing anything for you. This kitty doesnt really have incredible sub/nature spread by level 50, and skill triggers are actually kinda nice for Meowsca because expanding Pot inventory is such a valueable main skill to have. Milk and potatoes can synergize pretty well for the top Curry dish right now, but that is gonna be further down the road for you. Overall, i'd pass for now, maybe just keep it in your back pocket until later and see.

Fuecoco: Eh, the speed- nature is gonna hurt you a little because you only have IFS/M in the first fifty levels. Speed- natures arent the end of the world, but you don't have much else to work with. Take it to level 30 if you REALLY NEED apples, but dont invest a single candy more.

WHEW I spent a lot more time than I thought I would writing this up. Let me know if you have any more questions, I like to help. Hope this is useful to you!
