I used to break many, many cases of SPA each year.
I think that's over now, perhaps permanently.
I've moved exclusively into singles and honestly kind of reduced even that portion of buying/collecting considerably as we move ever further into what feels almost certainly like a massive asset bubble in cards with inflation/interest rate rises likely just a matter of time (together with some iteration of economic contraction).
All of those macro economic factors will reduce prices but it's not here yet; and what do I know: maybe it won't come at all.
At 400 USD for a pre-order per box of SPA when 19-20 was ~100 USD at pre-order, how do you reasonably justify that, particularly when the boxes aren't even guaranteed to have a FWA any more.
To the sidelines I go until the correction comes. And even then, I'm not in cards to chase returns but to make sets and have fun, and, at least to me, the current froth is the antithesis of both.
Not trying to yuck anyone's yum here, but just not my thing chasing crazy pricing and false scarcity.
