this hack has been incredibly enjoyable thus far and you deserve some major props, but we all know that by now.
i'm here to mention that there are a couple of pokemon that are unable to access really key parts of their moveset due to what i can only assume are oversights since there are 800+ available. specifically: minior can't get acrobatics, which is a huge detriment given that that's its only flying-type move and a key part of its otherwise limited movepool, not to mention the synergy with shell smash; alolan muk doesn't have access to the elemental punches, which while not devastating is pretty inconvenient as it doesn't have a lot of coverage otherwise; and it seems that the oricorio forms other than baile don't have access to any special tutor moves.
also, i'm sure this has been brought up before, but for the monotype achievements, it would really help if the game had a list of pokemon that don't break the achievement because they eventually evolve to gain the typing. things like corphish for mono-dark, alolan vulpix for mono-fairy, onix for mono-steel, etc. i understand this would probably be much more difficult to code, but it feels really bad going through a monotype run and realizing you can't add a potential member to your team because you can't instantly evolve it out of battle.
excited to see where this hack goes in the future and i'm particularly looking forward to hisui and possibly even paldea getting added; both regions add hugely helpful pokemon for monotype runs (scovillain, h-zoroark, h-arcanine, h-electrode, the tauros forms, pawmot, not to mention easier access to type combos like rock / poison and fairy / steel)
