Well, I don't normally play drafts. The deck I want to build, is something like a disruptive combo deck, if I am to be very precise. The idea is to have a healthy dose of detains and counterspells, and to deliver death by flying creatures ( I absolutely love Ascended Lawmage since the prerelease event I played ). I haven't actually tried it out, but this is my plan so far.
Orzhov, like I said, just isn't that interesting to me. I also don't know how to make it interesting. I like them thematically, and they have some great cards. They're even proving fairly effective for me, despite the fact my Orzhov deck is very much a work in progress. But in the end, the Orzhov playstyle just isn't that exciting to me.
Basically, I fell in love with disruptive combo decks when one of my friends built a Delver deck for me. I've been trying to build something similar ever since. The only reason I don't just build my own Delver deck, is I want to make something that's mine.
On a side note: Dimir are still very much my favorite guild, in all ways. I was fortunate enough to draw Mirko Vosk, the Mind Drinker. My god I love that guy. Mirko Vosk + Way of the Thief + Duskmantle Guildmage is a punishing combination, game-ending in a few turns if not dealt with. It's particularly vicious against decks that include ramping, because ... well, it follows that if you take out land cards of your deck at a higher rate than other cards, the average number of cards between the remaining lands grows.
