Not sure if it's just for this summer burst where they're offering two SEC cards a month (most months have only one, if any) or if it will be an ongoing change. However, the outlay required to acquire these SEC cards has dropped.
Typically, it has taken 1,500 outlay of credits to acquire an SEC card. Hasn't mattered if you're spending 1,500 on scratchers or wheel spins or bonus packs; that's been the threshold.
So for the first SEC trip last month, I figured I'd knock it out in one go and bought 1,500 credits of scratchers. My progress bar shot past the SEC card, shot through a gift card prgression, and partly filled an additional gift card progression. Realizing the system had been nerfed, I have been more cautious with the next two SEC flights. I didn't track the amount I spent on discount cards wit the second one, but have tracked it for wheel spins this round.
Eighteen spins (900 credits) is what it took complete the SEC progress bar. With those spins I won 200 credits back and was awarded 28 cards, which would have cost 420 credits. This translates to a 280 credit cost for the SEC card, above the 225 credit valuation we've previously determined via the DOLLZ joker card price. This tracks with my experience with other event games, where payouts will tend toward equaling outlays (including the credit value of shows received). A lucky session will end with you up overall, an average session has you laying out less than 225 credits for the SEC card, an unlucky session has you laying out slightly more than that.
Will confirm this with the next couple SEC events.
