Good article, and I for one welcome a weekly magic column. I've been playing since the original Mirrodin block, and despite it's issues (FUCK AFFINITY) I still loved it. Scars of Mirrodin was a nice return, but I have to admit, I'm a little bummed out that the plane that got me into magic has been wiped out and taken over by pure evil. And Venser (my favorite character) kicking the can was just depressing.
For standard, I'm running a White/blue/Green Birthing Pod deck, and it really get's some nice results. Skaab Ruinator is just hilarious. Also have two Commander decks, both control/combo, one with Vorash(G/U/B) and one with Crosis(R/U/B). The Crosis one is more for shenanigans, and pissing friends off with copying Cruel Ultimatum 5 times in a turn...I don't have many friends willing to play against it anymore.
As for you U/B deck, I gotta say, it's not doing it for me. Invisible stalker/swords just doesn't work as well as we all wish it would, it's just no Squadron Hawk.
For starters, one-of's in general aren't a good idea. Is that single Tezzeret really doing anything to reliably affect the outcome of your games? Why run a single Sword of Body and Mind/War and Peace mainboard? Are those two inkmoth nexus's really worth it when they're the only infect sources in the deck? Why do you only have one titan!? Control decks run on stalling till you get you bomb them, I know they're kinda expensive, but get some more Grave Titans, or maybe some Wurmcoil Engines in there!
Really now, it's kinda like you're trying to combine two types of decks into something that isn't working. You know what Invisible stalker likes? Mirran Crusader, Angelic Destiny, Geist of Saint Taft and Mentor of the Meek! A good U/W aggro deck just loves him. U/B control? Not so much. Maybe try turning it into a full on Solar Flare deck? Add some white, Fiend Hunter, Sun Titan, Unburial Rites, Think Twice, Forbidden Alchemy...you really don't "need" Snapcaster Mage for it to be effective, but I won't lie, it'd help.
