mtg sac a creature draw a card Greater Good - Magic (8093) sacrifice a creature.Whenever you sacrifice a creature Witch's Cauldron |B| Artifact. 1B,

You are usually going to get more than two manas worth of value out of the burn spell, but you do have cast the card for six, not four

That means the legendary creatures from Shadowmoor with hybrid symbols in their casting cost AND the legendary creatures from Fate Reforged with hybrid mana symbols in their text box will qualify, along with a single legend from Eventide

But theres always a chance that it puts in more work than youd expect, especially against mono-colored decks with a low curve, or if you encounter it alongside Painter's Servant

Until you invest five mana into it the card is just a 3/2 for 3 which is not at all good

Then the Carnage costs four and is a Blightning for one more

An aggressive card that's been just a little too slow to make it in the current Magic: The Gathering Standard meta, the artifact has cost around $0.50 for as long as it's been around
