Mono-Black Devotion was a powerhouse for some time last year, but the deck lost too many legs for it to stand on once Khans of Tarkir showed up
Each one represents a different moment in the story of The Lord of the Rings with six new-to- Magic cards

Chaos Warp Target permanent (land included) is shuffled into owners library The owner reveals the top card of their library and if it is a permanent, they get to put it on the battlefield Wild Magic Surge Destroy target permanent (land included) Its controller reveals cards from the top of their library until they reveal a card that shares a type with the destroyed permanent and puts it on the battlefield Chaotic Transformation Similar to Wild Magic Surge, but this exiles and instead targets an artifact, a creature, an enchantment, a Planeswalker and/or a land (yes all 5 at once if you want) and then reveals cards from the top of their library until they reveal a card that shares a type with it and places it on the battlefield Chaos Wand Pay 4 generic and tap it: target player reveals cards from the top of their library until the reveal an instant or sorcery card you may cast that card without paying its mana cost Wand of Wonder This is like a better version of Chaos Wand in that each opponent reveals cards, not a single target opponent

It just feels awkward in my opinion to have a deck so untrue to the character
In the right deck, perhaps Prosper, Tome-Bound or Ognis, the Dragon's Lash, this black wizard makes every spell you cast cantrip
