This past fall when I got back into collecting, I was pretty scatter shot. Panini Stars & Stripes, Topps Heritage, Topps flagship, BBM Japanese cards. I just bought stuff that looked cool without much thought to having any cohesion.
But, I did hit Topps flagship pretty hard and found that I’m close to completing series 1 and 2. I have some Update, too. But I haven’t sorted the Update base to see where I’m at there.
If you’re a modern set builder and you have a stack of dupes, feel free to take a look.
