Orzhov Midrange with Sheoldred for Standard

Forsaken Miner can return to your hand when you sacrifice a creature, allowing you to use its ability more than once. Corpses of the Lost creates tokens that can be sacrificed for the miner's benefit, creating a loop of value.

Sheoldred, the Apocalypse punishes opponents for gaining life while also providing card draw. Invoke Despair synergizes with this by dealing damage and allowing you to draw cards as well, amplifying the pressure on your opponent.

Evolved Sleeper can be upgraded during the game, and Bitter Triumph can provide additional card advantage while also creating a creature to sacrifice. This gives a good balance of board presence and card draw to fuel the sleeper's upgrades.

Graveyard Trespasser can exile cards from the graveyard while being a solid threat on its own. Falkenrath Forebear can return from the graveyard, providing a recursive threat and additional support for the trespasser's ability to keep the board clear.

Leyline Binding is a powerful removal spell that can exile creatures, while Field of Ruin can disrupt your opponent's mana base. Together, they can control the board while ensuring you have the mana you need, especially in a multi-color deck.
