I think it's just 8 extra rares/mythics per pod.

Assuming all the special guests are r/m, The List slot has 3.12% chance of being a rare.

About 1/7 (14.3%) foils is r/m.

We don't know the distribution of rarity in the wildcard slot, but I'll use the same distribution as the foils for a reasonable estimate.

That makes (3.12+14.3+14.3 ~=) 32 extra rares per 100 packs, or just under 8 per 24 packs.

Regarding the specific chances, considering they detailed the odds for the List spot but not the wildcards, I think it's more reasonable to assume chances are equal to the percentage of rares in a given set, which can vary dramatically, but I believe it's usually about 33%.

As for the math, I definitely went about it wrong (I was using 1-p^n^ for some reason, and I also did that wrong somehow). The right result would be closer to 16 rares per pod.

Sorry for the double post, but I thought you might be interested to see this.

MaRo has posted the odds. So looks like 8.88 packs per draft will have 2 rares, 0.96 packs per draft will have 3 rares, and <0.24 packs per draft will have 4 rares, for resulting in roughly (8.88 + 0.96*2 + 0.24*3 =) 11.52 extra rares per draft.

All good! Thanks for sharing. Ultimately still too much variation, imo.

I think it’s more reasonable to assume chances are equal to the percentage of rares in a given set, which can vary dramatically, but I believe it’s usually about 33%.

Why would they not adjust for rarity in this slot? They do it in all the other slots - it seems like a big leap to think that any specific common that can appear in this slot is equally as likely as any specific mythic.
