First, in a fictional setting, especially one that includes just about every mythology, and their magic/technology, out there, The author can take whatever liberties they want. "There just happened to be a secret facility Azazel never told anyone about that survived that has the capability to be adjusted into manufacturing the cards." Not to mention they'll almost certainly have Ajuka's support, and the Fallen Angels reproduction depends on the Angels, so they'll be even more invested (though, they're seemingly more content to die off, I'm sure there's going to be some interested in prolonging their species) They also don't have to develope the system from scratch, since they clearly have functional versions now, and as mentioned, Ajuka is there for support with tweaking if necessary. The only issues they have is reduced infrastructure for production, and finding usable canadates. Prioritizing and dedicating more reasources allieviates those issues along with whatever plot device the author wants to go with. Before, they didn't need to roll it out in mass scale that quickly, there was no urgency to repopulate and rebuild, it was just a convienient thing to help out later on. Now they have a reason to dedicate way more time and effort to getting the system functional. Especially when talking only a handful prototype mass-production test subjects in time for the tourny. I'm not saying the author will absolutley go this route, but the option's there. The important thing is Dulio is going to have a credable team backing him.
