Deck upgrade calculator

Pick cards or just set a rarity per slot — the cost depends only on rarity and levels, so you don’t need specific cards. Set current and target levels and we’ll count the copies and gold, plus the gems it takes to buy any copies you’re short of. Levels of player #UPCG8CL.

Every level costs copies + gold. If you don’t have enough copies, the missing ones can be bought with gems — so an upgrade is either copies + gold, or gems (for the missing copies) + gold. Gem prices follow the official table (December 2025), proportional to the shortage; gold itself is not converted to gems.
