No proxies but no print version?

I'm not opposed to proxies but I'd rather people support the games creators. All my local events allow proxies. Ideally the last few cards get to POD. My original question was more confusion around a no proxy event and the interaction with cards that have no official printing. I guess as a follow up, are the Baba Yagas via drive-thru not legal at say nationals but an ink jet are?

strictly speaking, yes. However the Tournament Organizer can choose to allow them.

The TO in a regional tournament allowed me to play with the first generation of Amaranth proxies so that Ke could get some feedback, so there's no harm in asking.
