Universes Within (SLX) and the corresponding Secret Lair cards aren't on Gatherer

In October 2021, the Stranger Things Secret Lair was released, and in March 2022, the same cards were re-released in SLX, an otherwise unnamed set that Scryfall named Universes Within. You can see all those cards here.

However, no version of any of these cards exists on Gatherer. That's even true for SLX, which doesn't use third-party licensed material.

• There are no cards with the text “friends forever” on Gatherer: https://gatherer.wizards.com/Pages/Search/Default.aspx?action=advanced&text=+[%22friends%20forever%22]
• Neither Arvinox nor Mind Flayer exists: https://gatherer.wizards.com/Pages/Search/Default.aspx?action=advanced&type=+[%22Legendary%22]&name=|[arvinox]|[%22mind%20flayer%22]
• Neither Havengul Laboratory nor Hawkins National Laboratory exist: https://gatherer.wizards.com/Pages/Search/Default.aspx?action=advanced&name=|[%22Havengul%20Laboratory%22]|[%22hawkins%22]

This means there is no Oracle entry or rulings available for any of these cards until such time they make it through to the SLX set.

This is true for the Street Fighter cards too. Let's take a look at Zangief / Maarika for example: Gatherer has no card named Zangief and no card named Maarika.
