So, uh, I'm not incredibly sure how hard it is to pull a Radiant in EN, but if it's anything like the Japanese pull rate, why exactly do you want Radiants to be meta-defining cards? There's only a handful of things the English TCG does right, and one of them is that any card that is extremely playable should not be extremely rare (or, if a rare print exists, it can come only if a relatively much easier to pull copy also exists).
e.g.s a Gold UR Trainer card invariably follows its non-holo common/uncommon print. A hard-to-pull alt art/rainbow VMax has a much easier-to-pull regular print VMax counterpart. Yes, there are exceptions you will be able to find, but they are the exceptions and not the standard.
Radiants have...only Radiants. There is no alternate, easier-to-pull print, and the fact only a handful of them are playable (and, by design, only as single card tech-ins rather than meta-defining focuses of the deck) is a good thing. A card that is extremely playable that is also extremely rare would be much more expensive as both collectors and players would be chasing it at the same time. We used to have to deal with this in older TCG blocks; I recall it being a problem during Gen 3 with myriad playable ex cards, even when the pull rate of an ex dropped down to 1-2 per box – to say nothing of several very good Gold Star cards. If you want a healthy competitive scene where things do not feel pay to win, you do not want to go back to that.
