You are mistaken in your calculations, which is understandable, You were thinking that D3 is “generous” enough to give us 104 cards (20 packs) for 600 crystals, brutal truth is that you only get 16 packs, 10 KLD 3 SOI 3 BFZ
Is it worth rolling the dice ?
I dont know, KLD should be pretty worthless to a new player who hasnt got HIXUS, Deploy, exert or any other “premium” mythics from earlier sets
I make it 16 packs (10+3+3) + 2 rares for 600 crystals.
previous big box was 14 packs + 1 rare+ for 600 crystals.
in sheer number of cards it looks like a decent deal.
problem is all the reward packs are now kaladesh. so
unless you need lots of cards in the kaladesh set there’s
not going to be much value in those 10 kaladesh packs.
