I think theres something to be said for a deck where the commander really takes a back seat for most of the game, even beyond the cool lore parallel to Saurons role in the books
Just look at cards like Tatoyova, Benthic Druid, who is a five-mana Blue and Green 3/3 that lets you draw a card and gain one life whenever a land enters the battlefield
Color Identity: W, U, B, R, G Cards Codie, Vociferous Codex High Alert Agatha of the Vile Cauldron Initial Card State All permanents on the battlefield
And finally, for those who seek the most luxurious form of universal power, the cosmic foil, textless version of The Soul Stone is for you
Consequently, it only makes sense that a massive tyrannosaurus rex card that lets you play all of your creatures at once would be a popular deck inclusion
I ended up getting a 42 one of these for my office and it stores my MTG collection plus my record collection pretty nicely
