This deck also needs creature token-oriented cards like Rootborn Defenses and Anointed Procession to augment the creation of God-Eternal Oketra's tokens
I hope the lucky owner of The One Ring riffle-shuffles it into their casual kitchen-table deck and then ties that deck up with a rubber band, because thats how TCGs should be games first, speculative market cash cows second.
That is where Ichormoon Gauntlet comes in
Exiling all graveyards stops a lot of problematic and somewhat unfair-feeling decks that rely on resurrecting expensive creatures for cheap
This game has gone through a great many iterations, and as such, quite a few cards are no longer ever going to be in print (save for the potential dissolution of Wizards of the Coast's much-maligned Reserved List which may or may never happen, due to promissory estoppel)
One utility land I always include in my decks, if my commander is three colors or less, is War Room
