The Planeswalker version, Nicol Bolas, the Arisen who can draw you two cards, deal ten damage to a Creature or Planeswalker, put a Creature or Planeswalker from any graveyard onto the battlefield under your control, and finally, exile all but the bottom card of a target players library
The card itself reflects this more thoughtful depiction, with ability Its Better This Way presenting two possible effects depending on Beast, Tragic Heros state at the start of each fo your turns
Endless Detour Instant The owner of target spell, nonland permanent, or card in a graveyard puts it on their choice of the top or bottom of their library
It should also be noted that certain cards, while they are published with an assigned rarity, are in fact released in products like Commander 2016 that have no relevant rarities since each sealed product is the same and contains exactly one copy of each card
Harmonize has a good effect, drawing three cards is good, although, costing four mana does make it on the weaker side of things
