Each pack is independent, so no product guarantees an SIR. “One specific SIR” assumes every SIR in a set is equally likely. No SIR rate yet for Astral Radiance, Crown Zenith, Evolving Skies, Lost Origin, Silver Tempest.

Reading these odds

“1 in 92” isn't a countdown

Opening 91 packs without an SIR doesn't make the next one more likely. Every pack starts fresh, which is why even a booster box can come up empty.

Any SIR vs. the one you want

Pulling an SIR and pulling the SIR you're chasing are very different odds. For one card, see how many packs or whether to just buy the single.
