Making items in store worth money

Hello guys, I was wondering why the decks for twist format was the only good items to buy in store right next to minisets? I think it would be good thing to put in store things similiar to twist decks that you could purchase and play with those cards also in wild because it is insanely expensive to make decks in wild since there is so many expnasions and so many legendaries that makes wild packs just scam. The only two items that were ever good were minisets and those twist decks.
