Bounty on MTG "The One Ring" reaches $2 million

Ending up in someone's closet without anyone else's knowledge would be the preferred outcome for Hasbro. Would keep demand for the product high so Hasbro gets to sell their full print run of collector boxes and game stores would make a killing by pushing the price up past 1000 per box. More likely is that the box the pack is shipped out in gets refused/destroyed.

The kid option realistically has no chance of happening. The card isn't in your normal 4 to 5 dollar booster pack, most stores charge 30 per or you can normally get a box of 12 for 230 (this set is already at 450ish per box). The other thing to remember is that this isn't pokemon. Young children aren't that into magic unless they were introduced to it by their parent who would likely be more aware of the card. Somewhat older children, tweens and younger teens, would probably know the value of the card because half of the content related to tcgs on the internet is money related/hypebeast adjacent.

Unknown, presumably WotC have some way of verifying the card is legit. That hasn't stopped countless Chinese and other counterfeits from popping up already though.
