Knowing Konami's actual potential speed, a card can go from concept to being printed in packs VERY quickly. Denial Deity Dotan being a blantant Elden Ring DLC reference to the final boss of that, released a few months after the DLC dropped is pretty fucking quick (DLC dropped June 21st 2024, Dotan was in ROTA in October 10th the same year so a little under 4 months), considering they'd need to conceptualize the card, get an artist to draw it, get it approved, then it get fully printed and distributed.
Even considering the over 2 month delay for BLMM in EU because of "clumping", its reasonable to assume that's how long it takes to get the various printing companies to print their shit. So you have to assume that a similar timeframe has to be taken out of the process for making Dotan too.
Which means someone in either the TCG or OCG played the Elden Ring DLC, liked it so much they wanted to make a card for it, and got it so fast-tracked that it appeared ASAP
