As with Sacrifice, Burnt Offering is great with cards that have high mana values that you can play on the cheap, such as those with Affinity or those that cost substantially less if you fulfill a certain condition, like Emrakul, the Promised End, Avatar of Fury, or Avatar of Woe

Thats why something like Chains of Mephistopheles is so pricy (because people like to pretend they understand what it does), and Soldevi Golem is straight-up worthless
