Modern Spotlight: Esper Zur
Esper Zur has seen some play over the ages, and is a very neat toolbox style deck when you can keep the namesake card alive.
The idea behind the deck is to play Zur, keep him alive, swing, and get a silver bullet that makes the game really hard for your opponent. Here’s the list that Lance Austin played in Atlanta:
This version runs fewer bullets than many of the older versions (which would often splash other colors for Blood Moon or something equally obnoxious). Detention Sphere is a great answer to most threats, Spreading Seas helps hose your opponent, and Steel of the Godhead makes you hit really hard (especially when put on a Geist). Ghostly Prison is really the only reactive bullet enchantment played, but it is quite good against decks that rely on having lots of creatures deal damage. The deck has tons of room for customization as well, since you can throw whatever CMC 3 or lower enchantments that you want into it.
After sideboarding you can very quickly shut down artifact based decks or graveyard based decks through Rest in Peace or Stony Silence. Other cards that I like to see in lists like these are Threads of Disloyalty or Bitterblossom, depending on the matchup. Wheel of Sun and Moon may be another option for graveyard hate that is one sided.
An important thing to remember is that you are essentially playing a midrange deck that can disrupt your opponent fairly well. Zur gives you options as to whether you want to disrupt them more, or if you would rather try to win as quickly as possible.
