Hi! When I started out/learned to trade up to rares I used the Rim method! It’s where you trade stuff for rims/rares and then trade those for clothing betas. After that, you trade the clothing betas for den betas! It might take a while but it’s how i was able to get an orange long and my first couple good rares. That’s my way of trading up! But i don’t really know any other good ways. Hope this helps!
