In the same way that, no matter what their setting, many of the Final Fantasy games have a duo named Biggs and Wedge in them, most of them have a Cid. Final Fantasy 7's Cid Highwind is the pilot of your plane, while Final Fantasy 16's Cidolfus Telamon is the outlaw whose hideaway becomes your base. They might be inventors or scientists, and they're often responsible for getting you the airship you use to cross the map at speed, but they're always Cid.
Magic: The Gathering's Final Fantasy set will represent many of the Cids of the series with a card called Cid, Timeless Artificer, which powers up artifact creatures and heroes you control. And, in defiance of the normal rule that limits you to four copies of the same card per deck—not counting basic land cards—you can have as many copies of Cid, Timeless Artificer in your deck as you want.
