mongst the most feared commanders I've seen over the years is Zur the Enchanter, but this is the first time I've seen him poke his head into other formats. He is actually Modern-legal, and as this list shows, possibly Modern-effective as well.
The very first question when presented with a Zur list is undoubtedly "What enchantments does he get?" The answer here is more concise than I would have expected, with the full main decklist containing only two copies of Steel of the Godhead and two copies of Detention Sphere. That may seem low, but an unopposed Zur will sometimes become enormous of off Steel, and getting to Sphere at least two permanents is a big swing. It doesn't take much more than that under normal circumstances, even though I'd probably be tempted to put a couple sweet one-of targets in, like Threads of Disloyalty or Spreading Seas (both of which do appear in the sideboard).
There are some interesting support cards in the deck as well, and the deck is pretty high on synergy even without taking Zur into account. Meddling Mage plus Gitaxian Probe, Thoughtseize, Remand, and Vendilion Clique means that the deck is very disruption-heavy, and may be the best Meddling Mage deck I've ever seen. Path to Exile gives the deck some instant-speed removal, and between Path, Probe, Remand, and Thoughtseize, the pair of Snapcaster Mages have plenty of good targets.
Geist of Saint Traft brings the beats, and is an awesome target for Steel of the Godhead, leading to some pretty easy wins. I even like the Creeping Tar Pits out of the land column, as they synergize quite nicely with the aggro-control nature of the deck.
The sideboard is awesome too, because Zur makes enchantments much more attractive. Spreading Seas, Rest in Peace, Rule of Law, Stony Silence, and Threads of Disloyalty are all legitimate cards in their own right, so adding the bonus of Zur searching them up is very strong. Illness in the Ranks I like as a tutor target, but that one is a bit more speculative in general.
