Not a fan of it being all upside. At a glance it doesn't seem as annoying as Initiative, but that's a low bar.

It's okay. I think it could have been named better.

I understand their reasoning for not having a downside as part of the main mechanic, but at the least I would have expected more cards to add a downside. Like some powerful mythic with a really strong effect whenever the Ring tempts you, but when it temps you for the Xth time you lose the game, something like that.

I plan on making the Lord of the Nazgul with a side of the Ring tempting my Wraiths. I think it will be a fun deck to play.
