It's right there. You're seeing the DMR print.

However, the Terminus of Return is *not* The Soul Stone. It doesn't have a flavor name, it has an altogether separate name. It has an altogether different type line and even different abilities. It's an “equivalent card”. (Which we're deciding to handle as a reprint.)

Count Dracula from VOW is *just* Sorin. It uses Sorin's name again as an indicator below the name bar, it uses Sorin's type line, it even uses Sorin's name in its text. (It would be a while later that Wizards decided to use the flavor name in printed text as well.)

The custom jokers on our homepage collage were lovingly rendered by @harkasab.bsky.social

Please give them a follow and some love!

Whoops, fixed!

We don't have historic changelog data like that, but Wayback machine would be able to help answer some questions. For example, it still has an archived copy of Lightning Bolt from before the Dominaria “any target” errata.

You might wonder: what's the deal with these sections in the Foundations gallery then? (scryfall.com/sets/fdn)

These are cards (mostly) specific to the respective product, but both products include cards from other parts of the set too. Some cards are in both!
