[2020] Worth Buying Cheap Booster Boxes for Digital Use?

Since I can upload my physical cards to the digital game, I feel like it's worth snagging up some cheap boxes while they're still in print.

I really enjoy cracking packs, so it seems like a cheap way to get some packs.

Also, where do those tribute cards come from? I got them in the starter decks that I bought on clearance, but none in booster packs so far.
