Hi, i didn't understand the mini set distribution. The new cards will be in the MDF pack after the realase (and when its suppose to happen)? Or there will be new packs just for the mini set? Or somthing else?
I have 10 packs and just don't know if i should save them or open now.
Duplicate protection is the key. From zero, with a new expansion without the miniset, it takes about:
32 packs for all commons
63 packs for all rares
174 packs for all epics
Every 20 packs should give a legendary (average, not a guarantee)
The miniset is supposed to have 35 cards and will be added to MDF packs. We do not know what rarity distribution it will have. Galakrond's Awakening was an adventure with 35 cards. It had 15 commons, 12 rares, 4 epics and 4 legendaries. With a similar distribution, it should take about 24 packs to get all of the commons and rares. That likely also comes with a few epics and a legendary.
How many packs to open really comes down to your goals. The miniset's commons and rares will have more value than duplicate commons and rares after your second that you may get now that you won't use.
I suspect we'll see it in January, but that's a guess.
With duplicate protection, I'm not sure how that could be accurate. Especially given that you can get/craft cards between when you get a pack and when you open it. If you already have all the MDF commons and rares, you should be guaranteed to get the new common/rares, regardless of when you purchased the packs. At least that's how I've always assumed it works.
