For example, the most expensive Street Fighter Universes Beyond Secret Lair card is Chun-Li, Countless Kicks
So it works really well in decks that focus on Mayhem and Madness interactions (letting you cast things for cheaper when theyre discarded) or Escape
Notably, the card is still legal in Commander, which means if you can nab a copy of this massively rare card thats never been reprinted, you can employ some truly chaotic shenanigans with any number of commanders that care about graveyard stuff
Shortly after this card was previewed, it dawned on most Modern players that this One Ring to Rule them All would become One Ring to Rule Modern for several reasons: 1) almost any deck can play it and/or wants to play it, 2) its ETB ability single-handedly shifts the state of the game, 3) it provides massive card advantage, 4) it's abusable
This is very helpful, as not only will it deal extra damage now, but it has better survivability too
If it changes zones, it will either cease to exist (if it's a token) or cease to be a copy (if it's a nontoken permanent), and so you won't be able to cast it as an Adventure
