EDH favorite Magister Sphinx is seeing its price on the rise.

The Magister Sphinx has always seen a lot of play alongside Sharuum the Hegemon and Oloro, Ageless Ascetic. The price jump may have to do with new copies being bought to slot into Breya, Etherium Shaper decks. The 4-color Legendary Creature from Commander 2016 is very artifact friendly, so its not a surprise that the Sphinx has become a good member of her 99. Breya's ability to deal 3 damage to a target player by sacrificing 2 artifacts becomes a lot more relevant when you can put a player down to just 10 life!
With Amazon's price on Magister Sphinx shooting over $6, it's clear that there's a real casual demand for this card. There aren't a ton of copies of the original Conflux printing of Magister Sphinx left on the Internet, either. If you're looking for this card, you'll want to get it while it's still $2 or less!
