'm taking a look at a new format this week: Return to Ravnica Block Constructed. It may seem odd to feature a format this late into its evolution, but it's precisely the timing that made me interested. When Standard does its big rotation, looking at the previous Block format is a perfect way to get a sneak peek at some of the potential contenders. In this case, we have a BGW Junk deck (not a judgment, just the common term for decks featuring this combination of colors), and it looks very much like a deck that could be adapted for the upcoming Standard.
This is a midrange deck at its core, and as such it has a mix of cheap to expensive creatures, with some removal thrown in. The curve is low enough that aggressive starts are more common than not, but I'd be hard-pressed to call any deck with Blood Baron of Vizkopa and Trostani, Selesnya's Voice anything but midrange.
The cheap set of creatures are all quite resilient. Experiment One grows large and regenerates, Voice of Resurgence is as ridiculous as a two-mana card can be, and Lotleth Troll is one of the harder creatures to kill. The three-drop spot is reserved for card advantage, with only Loxodon Smiter standing out as a pure stats card. Sin Collector and Varolz are both ways for this deck to go long without running out of gas, and both are crucial.
The expensive creatures are a mixed bag, with a combination of Blood Baron, Ghost Council, Advent of the Wurm, and Trostani providing the (presumably) perfect mix of threats. All of these creatures are good defenders, and it is easy to see how they can play offense against control as well.
Besides the four total removal spells, that's the deck. Against control, it's all about establishing a board presence early, forcing the opponent to react to it, and slamming one of the powerful four- or five-drops. Against aggro, all this deck needs to do is stay alive and Trostani or Blood Baron will eventually carry it to victory. Both of those approaches seem very reasonable come Theros, and I'd definitely look to update this deck with some of the new cards.
