Pokemon could do two sub sets instead of one per year, and instead of having them exclusive to box sets, they could release them like regular sets, but have each pack have 6 cards that are all holo, or something like that. These booster sets aren't treated like regular sets, and thus have no pre-releases, and theme decks.
Both Magic and Yugioh have these side booster sets.
Yugioh has 9 booster sets, 4 of which are the usual regular 9 card booster sets. The other ones are either the 5 card all foil packs that costs the same as a regular booster, or those 5 card non-foil sets that are cheaper than regular boosters.
Magic had the masters series, and still sometimes release a booster set that contains older reprints. The packs costs more than the regular booster sets. They also release booster sets that are not legal for standard, such as Conspiracy and Battlebond.
All I'm saying is, both Magic and Yugioh have side booster sets, and Pokemon only has 1, which is only exclusive in box sets, and not released as a booster box. It is time for Pokemon Company to make smaller main sets, and put those extra cards into a second side set, and release both side sets as a booster packs in a booster box, not in a box set.
