The card is only for new firearms (after September 2025). And certain firearms are exempt from even that requirement, the list reads like an arbitrary list from a video game, for instance, M1 Carbine, G-43, SVT-40, Springfield M1A, are not subject to the "ban" and wouldn't need a training card. (Although most FFLs out of sheer regulatory terror would probably require one and check regardless). It also exempts C&R, which many of the weapons identified in the list are already.... so IDK, typical contradictory authoring by people inexperienced in drafting bills as well as understanding firearms.
ETA: Also Inheritance does not require a training card under this act. The way I read it on first pass, I believe the approved list of instructors for CCW can also provide these training courses. Some counties, that's VERY easy to get on the approved list of instructors.
Both C&R and Antique are exempt. No further cake cutting, so yes. However- like mentioned, getting a LGS or corp store clerk to understand the tossed word salad is a battle that might be unwinnable and they likely will want a card regardless.
