It takes the normal Cube Draft formatin which you pre-select a pool of 360 cards, which stack in a rough square, to build your decks fromand attacks it with a permanent marker
That gets around the Forbidden restriction by giving you access to the card since it didn't start in your starting deck
That said, a 7 mana 7/7 you can give fire breathing with three seperate costs seems better than presumed in a 5 color deck, so the abilities at least gives it an upside than compared with others in the cycle
However, that five-mana difference materializes through two very real drawbacks: the cumulative upkeep cost of one generic mana, and the ability of your opponents to player it around it
Regardless of quality and how much paella the anonymous owner plans to eat, removing The One Ring from the pool of card possibilities will hopefully prick the ballooning price of collector booster packs and other MTG products where it might have lurked - collector booster boxes peaked at $500 for 12 packs on Amazon
The Warp is likely a bit awkward in terms of how to sequence, but still provides some additional flexibility and value potential that will matter in some games
