Depuis l'annonce de GvG c'est une question qui me trotte dans la tête... Et je savais que sur reddit quelqu'un m'apporterait la réponse ;)

Combien faudra-t-il acheter des boosters GvG pour avoir une chance d'obtenir les 120 nouvelles cartes?

C'est donc cette nuit que Bishey3 a apporté une réponse sur reddit

Tout cela est bien-sûr théorique et les statistiques sont juste un ordre d'idée pour économiser vos golds.

Voilà ce que son programme propose comme moyenne de boosters à obtenir :

2 months ago there was a thread here about a program that calculates how many packs are needed to complete a 100 card collection. (Link.) With goblins and gnomes expansion coming soon, I wanted to code a similar program that has a modifiable collection so I can use it anytime a new expansion comes out. I figured I would share it with you guys, and after that decision I added some other features as well. Here are some screenshots of the program. You can download it from here. You can also see the code written in C++ here. (Warning: I've started coding in C++ only a few months ago so the code might be a bit messy)

Here are some of the results for certain sets with 10,000 simulations.

Expert Set (C: 94, R: 81, E: 37, L: 33)

• Average packs needed to complete the regular collection: 462 (Extra cards + all golden cards disenchanted)
• Average packs needed to complete the regular collection: 517 (Only extra cards disenchanted)
• Average packs needed to complete the golden collection: 2548 (Only extra cards disenchanted)

Potential Goblins and Gnomes Set (C: 47, R: 40, E: 19, L: 17)

• Average packs needed to complete the regular collection: 213 (Extra cards + all golden cards disenchanted)
• Average packs needed to complete the regular collection: 247 (Only extra cards disenchanted)
• Average packs needed to complete the golden collection: 1260 (Only extra cards disenchanted)

Now that the results are out of the way, let's talk about the program. First of all let me tell you what this program can't do:

• It doesn't have a graphical user interface. It operates completely on the windows command prompt. However it has a usable menu and hopefully a generally user friendly structure.

• It can't show you which cards you get from a pack. Since it has a modifiable collection it would be too complicated to implement (for me anyways) cards with names or even pictures attached to them.

• It also can't do many other things.

Here is what it can do:

• It can open individual or multiple packs, one by one or all at once. It will show the user the card rarity distribution in the pack(s). (Remember all in command prompt.)

• It tracks which cards you open in a certain rarity even though it can't show you it's name. At any point you can see how is your collection is going. It shows how many cards you have 2 copy of, how many you have only 1 copy of, separated by their rarities. (Golden cards are also counted)

• You can change the number of cards in your collection at any time and also you can change the percentage at which different rarity cards drop. You can view these values at any time.

• It can disenchant extra cards. (2.+ copy for legendaries and 3.+ copy for everything else). It can also disenchant all the golden cards if you choose so.

• It can craft regular cards or it can craft golden cards. While crafting you can choose to use your dust completely or prioritize higher rarity cards first. (E.g. No epics will be crafted until legendary collection is finished)

• You can reset your progress at any point.

• It can open packs until your current collection is finished. This option automatically disenchants extra cards and crafts new cards.

• It has a separate option for just completing collections over and over again. In the end it will tell you on average how many packs are needed to complete a collection. In this option you can choose to complete regular collections (this will disenchant all gold cards automatically thus decreasing the packs needed). Or you can choose to complete both a regular and a golden collection. (Only extra regular and golden cards will be disenchanted. Packs needed for the regular collection will increase)

Here is a few things the mention about the crafting system. I'm not really sure what would a realistic crafting function would be. At the moment it starts from crafting legendaries. It will not craft epics until legendaries are completed. (Unless specified otherwise in the disenchanting menu) It will not start crafting rares before it finishes the epics and etc. Now this is the almost most ideal way for crafting cards. You start by crafting the ones you have least chance to find in a pack. However this is not a realistic way of crafting cards in hearthstone. And this most definitely affects the end result about the packs needed.

So I am open to ideas here. If you describe me a realistic crafting system (e.g. craft 10 legendaries, 20 epics, 30 rares before the other cards) I can try to implement that as an option. However you should keep in mind the collection size is changeable so the number 10 is only relative. Maybe 1/5th of the legendaries or something along those lines could work.

On a side note, the program has 10 options in it's menu. I fear the it might be too confusing for the user. Therefore I am considering taking the "Exit" option out of the program.

Feel free to leave any sort of feedback. It can be about design, the code, the mathematics or anything else really. Hope you find the program to be useful.
