Notes from the Headghoul on the Diamond Dynasty market.
Across the 40 content drops I could measure this season, non-Live diamonds worth 5,000+ stubs were cheaper the day after than the day before on 28 of them. Big themed drops hit hardest. And the overnight discount I said would vanish on drop nights didn't.
A major Postseason update arrives with new cards, packs, and seasonal content for Diamond Dynasty players.
I went through every roster update SDS shipped for MLB The Show 26, card by card, to find out which ratings actually move an overall. Most OVR moves are tiny, power drives hitters, and two of the biggest drivers for pitchers aren't in SDS's update list.
Picked by the Diamond Radar score showing on the day you'd actually have bought, cards scored 70 or better returned a typical +333 per 1,000 stubs bought a week before a roster update, against +62 bought the night before. And flipping them before the update lands gives almost all of that back.
Diamond Radar's first season of grading went through three scoreboards: a bare hit rate, a hit rate with the chance rate beside it, and grading by score band. Here's why each one was replaced, what the page says today, and how to read it.
Mobile Diamond Dynasty expands with classic player cards, new events, and themed pack drops.
On October 2, cards with a Diamond Radar score of 90 or better upgraded 39 times out of 41, and the top ten of the board went ten for ten. And the players who weren't playing, one of them left on the board on purpose, showed exactly what the model needs to learn next.

New progression rewards, classic matchup, and fresh Spotlight cards headline this week's Diamond Dynasty content.
Across all five roster updates we graded this season, cards with a Diamond Radar score of 90 or better upgraded 78% of the time and averaged the best result on the board. They also produced the most expensive misses on the board. Both of those are true, and the reason is the week before the update.
Multiple programs and events launch simultaneously, offering fresh card opportunities and rewards this weekend.
63 of the 77 cards that crossed a rarity line on September 11 had a Radar score of 50 or higher, and all four +8 jumps scored 83 or better. Nick Kurtz scored a 96 from the 60-day injured list and didn't move an inch. The lesson: a score is a chance, not a promise.

Ketel Marte is a 90 today and he was a 90 in March. He cost 100,000 stubs then and 8,480 now — down 92%, without losing a single point of OVR. Jeremy Peña, an 85 who cost 3,730 in March, is up 7%. Nine cards, none of them re-rated, and the only thing that predicted the damage was the March price.
