Omg pre release/early prices are always going to be rediculously high! Unless you're playing in a pro tour/gp/other major event DO NOT buy cards at prerelease prices. If you wait at least a month most times prices drop significantly. The only time it's worth buying at prerealese is if you're specing on some foils of cards that are being over looked but have great potential. Every set has those few common and uncommon foils that end up spiking a 1000%.
What is the point in making videos like this before the set is even out. The lion share of these cards will go down significantly when these boxes and packs are open en masse.
A lot of the reason I make these videos so far out is that it is almost an indication of the top 10 most powerful cards in the set. That is why a lot of the focus is on what makes the cards so good.
Dude, prices before release are meaningless, like really really meaningless, people have no idea how to value cards nor do they have opened any, nor do they sold any, so they don't know the overall playability, demand and scarcity of those cards. As a recent example, Strixhaven had 10 cards above the 20$ threshold one week before release, now the most expensive by far is liliana and she's about 13$, everything else is under the 10$ mark, so yeah...
