Tournament prize-payout via store credit, how does it work on Magento?

Local Game Stores (LGS) running MTG Friday Night Magic, Pokemon Play! events, Yu-Gi-Oh Locals, sealed Pokemon prereleases, and ComicCon side events need a prize-payout flow. Cash is bad (margin drain, AML paperwork at scale); store credit keeps the revenue inside your ecosystem and incentivises repeat visits.

Pattern I default to:

• Magento gift card / customer balance, store credit issued as a customer-balance top-up. Customer wins $20 at Friday Night Magic, gets a credit notification email, comes in next week and spends it on sleeves + a Booster Box. You keep the margin, they leave with new product.
• Tournament organiser admin role, limited admin permissions: can issue store credit, cannot edit products / orders / customer PII. Safe for the LGS event-runner to use without giving them the full keys.
• Reporting, WPN (Wizards Play Network for MTG) and Pokemon TCG Professor program reporting compatible. CSV export of all prize payouts for the month.
• Multi-format support, Standard, Modern, Legacy, Commander / EDH, Pioneer for MTG; Standard + Expanded for Pokemon; OTS + Locals for Yu-Gi-Oh. Format gets stored on the event record so post-event analytics work.

Customer balance can also stack with promo codes, FNM regulars accumulate $200, $500 in credit by year-end, then spend it on a sealed Booster Box during the holiday sale. The flywheel works.
