MTG Salvation

Step one, Witch's Oven. Step two, get a cat. Bake the cat into a pie. Feed the pie to the corpse of the cat. Cat is now alive again. Wash, rinse, repeat.

Ayara, First of Locthwain + Cauldron Familiar + Witch's Oven + Syr Konrad, the Grimm in a mono-black artifacts deck is going to be an interesting engine that I will be trying out. Ayara and the familiar ping the opponent for 2 when the familiar enters the battlefield, then you sacrifice the familiar to create a food with the witch's oven, revive the familiar with the food token to ping for 2 more, and sacrifice it to Ayara to draw a card. As long as you have a food, you can repeat this same strategy for no additional mana, pinging for at least 4 and healing for 4 while drawing a card (or not drawing to create a spare food to continue the cycle). If you can stick Syr Konrad, the Grimm, each cat that dies or revives also pings an additional time. Additionally, each Witch's Oven you play increases the damage by at least 2 each cycle, not to mention if there is a way to untap it reliably in the yet to be released cards (unfortunately, Voltaic Servant is rotating out).
