Deadguy Ale is probably the most famous midrange deck in the format and also one of the most resilient. The power of the deck comes from combining great and diverse threats with a plethora of removal for whatever the opponent does. The aggressive part of the deck consists of threats like Juzam Djinn, Hypnotic Specter and Underworld Dreams, often combines with Dark Ritual to deploy them as fast as possible.
The threats are backed up by some of the most efficient removal in the format in the form of Disenchant and Swords to Plowshares. It's also not unusual for the deck to play Sinkholes to attack the opponent on one more angle and sometimes you can see lists splashing red which gives it access to Lightning Bolt for more removal and Red Elemental Blast for better game against blue decks.
