Here’s an excellent spreadsheet that show the cost of paying for an Arena vs. Buying Packs.


  • If you get more than 4 wins on average in arena, money spent in arena gives you a much better return than buying packs directly
  • Even if your average win is less than 4, you only get between 15-20 % less packs than arena –> it is STILL worth to play arena, to improve and eventually become a ‘winning player’
  • Never spend your gold on additional packs – unless you are a ‘winning player’ that gets 7 or more wins on average on arena (less than 0.1 % of playerbase)
  • The only reason to purchase packs is to speed up the process. Getting packs through arenas is very efficient, but takes time
  • If you consider opportunity cost (for example you could spend the time playing arena on overtime in your job, making $100 per hour – buying packs might be the best, but please also consider the fun aspect of playing arena
