You're right about the premium treatments and the pricing. I don't think the fact that 4 out of 10 tier decks are under 200 bucks will bring more people to standard though: if you're on a budget you look at the standard metagame and see that you can sleeve up mono red aggro for under 100$. But at the same time you see that you'll never be able to afford other tier decks like golgari or esper midrange, which are about 500$. If you don't have access to the option of creating the tier deck you want, only the tier deck you can afford, it creates a feeling of being locked out of (part of) the format, and creates resentment toward those that càn afford a golgari midrange deck.
