Recently occurred to me that while indestructibility has long been around, we haven't really seen any card ability or game state preventing something from being exiled/removed from the game.

If I'm misinformed and there _are_ some cards from much earlier in MTG's timeline I failed to find on my recent cursory google search, I trust I'll be educated shortly. But if this really hasn't ever been a thing, then why not? The more I think about it, seems like a perfectly viable (without being remotely OP) effect for something to ignore exile effects (while remaining perfectly destructible otherwise).

Initial thoughts on what to call something like this are "soulbound" or "tethered" but I'm sure the more creative minds on this subreddit can do better (again, assuming this hasn't already been a thing historically).
