Grave Rune OTK/Combo Priest

What sort of expansion could go by without a greedy, greedy combo deck theorycraft? But this one looks less crazy than most! It exploits the interaction between Grave Rune and Shadowy Figure to summon entirely too many Leeroys, Cubelock style.

The classic Northshire Cleric/Wild Pyro/Acolyte of Pain/Circle of Healing/PW:Shield Shell provides card draw and anti-aggro. Mass Hysteria, Forbidden Words, Penance, and Time Rip provide extra removal. This deck runs Galakrond to discount combo pieces with Fate Weaver, and Galakrond, the Unspeakable even provides an extra boardwipe.

When things come together, play Leeory, Grave Rune, and Shadowy Figure to summon up to 7 Leeroys (plus 2 2/2 Leeroys). You can even pop your own Leeroys using Breath of the Infinite. And you don’t even need to hit every possible combo piece with both Fateweavers: discounting 2 or 3 pieces by one or two ticks is good enough, depending on your opponent’s health and board.
