Do you have any tips for raising/training the Trapinch line? I plan on raising one into a Flygon for my team and I want some advice on how to raise them.
Sand. You need a lot of sand!
Dirt can work as well, but you really need to let them thrive in their sandy environments so they can gain the experience they need to really hone their abilities that only they can do.
Once Trapinch evolves, then they can practice more areal combat and focus on overcoming new climates.
You'll also want to make sure you have tough things that they can bite, as they just have urges to bite and need to flex that jaw strength.
Invest in some high-quality goggles to keep sand out of your eyes, especially if you are doing intense training, you'll thank me.
If you're traveling with one, note that they will probably want to burry themselves in soft soil, which they can vibrate into sand, so try and teach them good habits to fill in holes.
Ultimately, other than learning their habits, their training will be pretty straight forward, however flygon are interesting as they are speedy flyers but not really high flyers, so be aware that they might not want to always soar, it doesn't mean anything is wrong with them, they just really enjoy the ground as much as the sky so they may have a preference.
