Tips for Tr4ding. (I'm just using the bypass since this isn't an actual LF pet post)

Hi there, returning after a good while. I'm just so confused on how to actually trade my pets and make better deals. All everyone wants seems to be "TITAN NM COLOSSAL 3M KG" whatevers. I thought Kitsunes and Raccoons were a big thing but I can't seem to find a single good trade for them. Does anyone know how I can actually start trading and making w's instead of sitting in a corner with minimally good pets? Thanks :) <3
