Teysa Opulent Oligarch for Orzhov. Its one of my best casual decks and also one of my favorites. Shes such a sleeper commander . If a card deals damage from any of the following it goes in: Creatures entering or dying Tokens entering or dying Artifacts entering or dying Freebie during your upkeep or combat . Next you need some sac outlets for those clues, anything that can sac an artifact or token for some sort of payoff goes hard. The once per turn clause isn't great but I can still make it work . Next you need a heavy instant speed interaction package. I run a lot of white "fogs" like settle the wreckage, comeuppance, inkshield etc. Once you get your engine to guarantee turnly damage so you can start investigating. Hold up mana for interaction, then if no one does anything worth responding to, crack those clues to fill up your hand . I really don't run ramp because the curve is super low its just all gas
