The regular reprints have a lot of value for angel decks like Angel of Destiny, Archangel of Tithes, The Book of Exalted Deeds, and Serra Ascendant, plus important mana base cards like Emeria, the Sky Ruin, Nykthos, Shrine to Nyx, Urza's Incubator, and Pearl Medallion
As a result, Mentor of the Meek makes a perfect addition to token decks with mana to spare
Any time you are looking at building an artifact themed deck in blue, Urza, Lord High Artificer, should always be on the consideration pile
A 3-mana Disenchant isnt bad, and the ability to use it for free is nice gravy on top
So if you're playing a one-for-one game, where they play a creature, and you make them sacrifice it, eventually you're just going to have numerous copies of Chainer's Edict in the graveyard waiting to do it all again
Minimal hoops to jump through: You shouldnt have to go through several steps to exercise your reanimator commanders full potential playing the card and then doing up to 1 thing should result in a contribution to your game plan
