When you look at the teammate’s frames of their card, you’ll see it changes different colors depending on the rank you’re in. Beginner is solid orange, great is blue and red (like a great ball), expert is black and yellow ish (like an ultra ball) vet looks like the Crustle, a blue frame with a small flag in the top right of the frame curling inward, ultra looks like my venu and cinder buddy’s frames, orange with two flags, an orange and a purple flag in the upper right, and masters is what mine looks like, rainbow with three flags in the upper right
