Only Magic: The Gathering has the design space to do something like this - where the return of an old mechanic actually feels very in-universe, and like a subtle inside joke, as well
For example, the release of high-value Pokmon sets or the latest Pokmon chase cards can drive market buzz and higher prices for related older cards
These were double faced cards that allowed you to play either side as you saw fit - one side was a somewhat overcosted spell, one side was an enters the battlefield tapped single color land
When the timing is right, it can also sacrifice itself to protect your board, so its both a strong deterrent and a safety valve
Just keep casting your big creatures and so long as they have power 4 or greater, you'll be able to draw a card when they enter the battlefield
There are countless artifacts that give you value when sacrificed, like Myr Retriever and Chromatic Star
