As you're going through, you'll have a chance to read the cards and see what interests you
Im also ditching Emeria Shepherd and Dawnbreak Reclaimer in favor of Karmic Guide when it comes to recursion

If adding a single red mana one time for free is too good for Modern, then cards that repeatedly offer free mana (Chrome Mox, Eye of Ugin, and Mox Opal) or offer a one-time burst of more than one mana (Seething Song and Summer Bloom, which was primarily used as a ritual with bounce lands in Amulet of Vigor decks) are too good as well
Its also just a huge beater that's very, very hard to get rid of
