Picking Cards Up Off Of Their Floor

Here we are, with a new set about to drop and once again, I’m having to divide my attention between the things I want to buy for myself and my decks, and the things I’m buying in order to sell later at a higher price.
The rule for the first category is to be as patient as I can, as explained by the second rule: It takes about six months, or roughly two major sets, for cards to come down to their lowest price. It hurts to know that if I’m adding a new and sweet card to a deck, I’m going to be spending more than I need to.
For example, on September 12, I bought a Foil Extended Art Defiler of Vigor, for my Zaxara, the Exemplary deck. Defiler does two good things, both letting me spend life in place of mana and increasing my Hydras’ number of counters with every spell. That Defiler cost me about $15, let’s see where it is now.
Ouch, nine bucks. That’s not too bad, but it stings all the more to know that I’m probably going to take the card out soon, as it hasn’t lived up to my hopes in Commander. When I buy cards for personal use, that’s the risk I’m taking. I accept it, I let the desire for the new toy cost me more than I would otherwise spend.
My purchases for later resale, though, that’s a different matter. I want my buy-in to be as low as possible, so that my profit may be more easily realized. So if I’m waiting two sets, that leaves three major groups of cards: Double Masters 2022, Commander Legends: Battle for Baldur’s Gate, and Streets of New Capenna.
Some caveats: In this era of Secret Lair Drops, of a dozen Commander decks a year, I need to be aware that the reprint risk has never been higher. That’s just the presumed risk underpinning all of this. No help for it, no predicting it, and nothing to do but diversify in the face of it. Foils with special frames are less volatile in the face of reprints, but there’s no guarantees here.
Ideally, I’m looking for cards with high EDHREC numbers, not a huge cost, and hopefully some appeal in formats outside of Standard. I’ve learned to avoid Standard-based specs, just because paper play isn’t all the way back yet.

One thing to note about CLB cards is that the market does not like these showcase foils. Almost across the board, showcase foils are notably cheaper, in foil and in nonfoil. There may come a time when the regulars are so expensive that they drag the showcase versions up, but mostly, the Monster Manual frame is unpopular.

Double Masters 2022
As a reprint set, the numbers for inclusion are a lot higher, but this is the perfect time to buy low for all the decks that could use a given card.

The chart tells the tale: the card started out over $100, and has trickled downward to its current price, which in a special frame and in foil, is a very safe bet to regain at least $20 in value, depending on how long they wait to reprint the card. Another reprint is inevitable, only question is when.

I want to highlight two cards as things I’m avoiding: The Triomes from SNC are in line with the Ikoria versions, and so I don’t think there’s much profit to be gained there. I’m also certain that there will be a ten-card matched set Secret Lair for the full set, much like we got for the shocklands.
I’m also staying away from Chaos Warp
