Important information regarding Breeding on TheNodeMC
Most info you may require regarding breeding can be found on the Pixelmon Wiki.
Notable changes from the above:
Hidden Abilities will not pass down to an egg unless the breeder is the OT of both parent Pokémon.
Requirements will dynamically change based on the total IV percentage of the parent Pokémon you put into a Daycare box, so they will become harder to breed as they increase in power. In some cases this may mean requirements being added to the original set, such as Type Gems!
In addition to normal drops, you can also get Type Gems from Gem Bags
