Explanations (Designs and Aesthetics):
Artificial - Related to machines, technologies, electronic devices, buildings, and other types of man-made objects.
Ghoul - Related to ghosts, goblins, witches, fairies, and other fairy tale monsters.
Piscine - Related to fish and other aquatic animals.
Reptile - Related to reptiles, amphibians, and animals with reptilian characteristics.
Slime - Related to sticky substances, slimes, and diseases.
Mineral - Related to rocks, gems, and metal ores.
Beast - Related to mammals and animals with mammalian characteristics.
Arthropod - Related to insects, arachnids, and crustaceans.
Avian - Related to birds and other flying/gliding animals.
Plant - Related to plants and fungi.
Explanations (Type Matchups and Immunities):
Artificial -> Avian: Birds sometimes crash into buildings, windows, and other structures.
Artificial -> Mineral: Machines are used to destroy rocks and dig up minerals and ores.
Ghoul -> Plant: Some ghouls can be considered monstrous entities that harm nature.
Ghoul -> Artificial: Ghouls and spiritual entities are infamous for tampering with technological devices and machines.
Ghoul -> Beast: Ghouls are typically smarter than beasts and as such they would be able to outsmart or tame beasts.
Piscine -> Piscine (self weak): Many aquatic animals eat other aquatic animals.
Piscine -> Ghoul: Fish meat smells bad and I'm pretty sure spiritual entities, much like everyone else, do not like horrible smells.
Reptile -> Mineral: In some stories, reptiles (especially dragons) are known to steal and horde gems and crystals.
Reptile -> Slime: Many reptiles have strong immune systems that would allow them to overcome diseased or sticky entities.
Slime -> Slime (self resist): I imagine that slimy substances would mix together rather than having one substance overcome and completely dissolve the other.
Slime -> Beast: Sticky substances can easily get caught in the fur of mammals and weigh them down.
Slime -> Mineral: Acids and bases can be used to dissolve rocks and minerals.
Mineral -> Ghoul: Crystals and gems are thought to ward off evil spirits.
Beast -> Beast (self resist): Many mammals have loose skin so they have less of a chance of being injured from scratches and bites.
Beast -> Reptile: After the extinction of the dinosaurs, mammals took the title of the dominant animal group from the reptiles.
Avian -> Arthropod: Many flying animals such as birds and bats love to eat bugs and spiders.
Avian -> Slime (no effect): Sticky substances can easily get caught between feathers and prevent birds from flying. This would make avian Pokemon hesitant to attack slime Pokemon.
Avian -> Piscine: Many birds eat fish. It would be hard for an aquatic animal to attack an airborne animal.
Plant -> Plant (self resist): Many plants live in close proximity with each other and as such they must be able to survive the negative effects of neighboring plants.
Plant -> Artificial: This is the most interesting matchup since most people would say that Artificial beats Plants, but I wanted to try something different. It is true that human technologies can destroy and harm plants and nature itself, but plants and nature can overcome human technologies and machines. They can survive and even thrive in man-made environments (examples include vines that cling to the sides of buildings and weeds that grow in between the cracks in driveways). When plants and machines are left to their own devices, the plants take over and grow all over the machines (just look at pictures of cars that are left in the woods). After there is a natural disaster, nature recovers way faster than we can and even takes over abandoned towns and cities. In the short term machines beat plants, but in the long term plants beat machines.
Explanations (Statuses and Immunities):
Acid - Acids can resemble flames because they both have the ability to burn things. Slime Pokemon would be immune to this because many Slime Pokemon would already be considered acidic.
Bleed - Much like poison, this would drain a Pokemon of their energy and make them lose health. Beast Pokemon would be immune to this because mammals have loose skin that helps lessen the chances of receiving nasty wounds. Piscine Pokemon would be immune because water can help with blood clotting and all fish have a slimy coat that helps in the process of blood clotting.
Severe Bleeding - Kind of like bleeding, but much more severe.
Chilled - It is hard to move when you are cold. Beasts are immune to this because mammals are warm-blooded animals and as such they can survive in cold temperatures (I would've loved it if black/avian was immune to this because birds are also warm-blooded animals, but that decision is completely out of my control).
Hunger - Sometimes you are so hungry that you barely have the strength to move (or is that just a trope?). Reptile Pokemon are immune to this because many reptiles have a slow metabolism. Having a slow metabolism means you do not have to eat often. Some reptiles can go months without eating.
Dust - Dust is not much different from powder. Many ghouls tend to be in dusty places such as abandoned buildings, so they must be able to tolerate the dust particles.
