If you can get about three Aunn cards in 100th black market, your magic circle's duration becomes basically infinite (because you can spam them constantly - Aunn reduces their cooldown time). The magic circle slows bullets that hit it, and may even stop them entirely based on your card spread.
Sukuna's ability is to turn bullets into Funds (aka the Long-Term, cross-runs money of 100th Black Market) using the mallet marisa's holding, and Komachi's spell card is an extremely dense wave of bullets, centred on herself and expanding outwards.
So it looks like Marisa's found a money-grinding strat.
