Many Middle-earth cards use "becoming the Monarch" or "The Ring tempts you" mechanics

Firstly, you can get a trigger from Seifer the same turn you play it by attacking with a different creature, so thats already a good impact on the board

Timeless Witness Timeless Witness is a cool homage to Eternal Witness, both in the artwork and in the clever use of Eternalize

It works really well in decks running colorless bombs like Eldrazi creatures, Karn Liberated, or Ugin, the Spirit Dragon

It also has the added bonus of allowing you to untap all your creatures outside of your turn, serving as an excellent defensive tool if you have the mana to spare
