Mono-white decks likely have space for it, but there are better things to do with this much mana most of the time, including casting other angels
This trading card game, released in 1995, is incredibly aesthetically beautiful, and much of its artwork was actually done by the artists whose work appears in the Lord of the Rings books
You can find my other precon upgrades here: Ahoy Mateys is a Blue / Black / Red Pirate deck: the goal of the deck is cast a bunch of pirates and go attacking, looting your opponents for treasure (Malcolm, Keen-Eyed Navigator), stealing their cards (Ramirez DePietro, Pillager), and even their permanents (Admiral Beckett Brass)
Oh, and it provides card draw and life
