More info
The Blank Voucher appears to “do nothing” when purchased, but its real function is meta-progression: buying the Blank Voucher ten times across any number of runs unlocks the Antimatter Voucher, which gives an extra Joker slot (+1) for runs where it appears. This is explained on the developer’s site and covered in community write-ups, which note the Antimatter upgrade as the Blank Voucher’s hidden reward (official Balatro note, Destructoid guide).
If you’re hunting the unlock, remember a few practical details players report: the purchase counter is tracked across runs, each Voucher normally costs $10 in the shop, and Antimatter will only be offered in a run if you buy the base Blank during that run once it’s unlocked. Common routes to reach the ten purchases include repeatedly buying Blank across many runs, using the quick “buy then return to menu” trick to increment the counter without committing money, or using the in-menu “Unlock All” option (which disables achievements). For more on the trick and unlocking methods see this community write-up (TheGamer walkthrough).
