So about these puzzle pieces...
I havent seen any other posts about this, so I'm interested in your feedback. Be warned: this is a long-ish math post.
Please correct my math if I'm wrong, but to make a white card we need 6 puzzle pieces, which needs to happen 15 times to get a blue piece, which needs to happen 6 times to get a blue card, which needs to happen 3 times to get a silver piece, which needs to happen 6 times to get a silver card. So:
6 × 15 × 6 × 3 × 6 = 9,720
9,720 white puzzle pieces required to make one silver speckle card (or 1,296 green pieces). Which means it would take...
9,720 × 3 = 29,160 white pieces
- or -
1,296 × 3 = 3,888 green pieces
...to make a single gold card. Given that you get one uncommon per pack, and assuming you end up with the same number of each piece (never gonna happen), or trade until you have the right number of each piece (so much trading), you would spend a *minimum* of...
29,160 × 3,000 = 87,480,000 coins
...for a single gold card. Or 77,760 diamonds using green pieces from the super pack, or $1,553 and change (the math wasn't as neat for these two, I think it would actually cost more since these two numbers involve theoretical partial-packs) of *real money* using green pieces from the $9.99 bundles.
All of this is of course complicated by the possibility of getting occasional green cards in coin packs, and white cards in diamond packs, so this is all untimately ballpark estimates. I would love to be told that I got all of this terribly wrong, because... wow. It's a lot.
TLDR:
29.16 million coins for one complete silver card, 87.48 million coins for one complete gold (if youre primarily using white pieces) plus a bunch of trading to make sure you have the right number of each piece.
