Overall, it’s not a bad creature. With the Minotaur lord Rageblood Shaman pumping it +1/+1 and giving it Trample, it’s actually a fairly effective creature on offense. In addition, Ragemonger can make it cheaper to cast by one Red mana, often making it a three-drop.
As Minotaur decks run a fair share of burn and removal spells, there’s a good chance that an opponent actually pays the Tribute cost. But did Oracle of Bones actually see much play during its time in Standard? Really, it didn’t see as much play as you’d think. Outside of Red Deck Wins in Theros Block constructed, it only saw real competitive play in the occasional Jeskai Tempo or Boros Aggro deck.
Since his time in Standard, Oracle of Bones has only seen EDH play in Minotaur Tribal Commander decks such as Neheb, the Worthy and Mogis, God of Slaughter. This Minotaur probably should have seen more play than he did and he’s a great choice to consider for any Minotaur deck.
