Elenda, the Dusk Rose If you want a generally powerful sacrifice commander in Orzhov, you cant do much better than Elenda, the Dusk Rose
Its also an up to ability, so you wont be forced to nuke your own pieces if you want to pump more mana into it to get more tokens

We recommend choosing codes in a standard format for immediate playability
Also Ghost Quarter and Field of Ruin become re-usable with the Crucible (Against non-basic heavy decks, you can even quickly run them out of basic land by re-using the Field) Other possible picks along your lines: Custody Battle gives you a form of Creature Control, but works best when you have a sacrifice outlet for them like Thud, Fiend Artisan, or Birthing Pod so that you don't have to give them back after attacking Destructive Urge is a nice Land-related enchantment for one of your Trample creatures forcing your opponent to block every point of damage each turn Shivan Wumpus is another nice Trample creature with great Power/Tough for his mana cost
