This is my Prossh deck. I've made a lot of substitutions since I originally bought it, and it works like a charm now. This deck works off getting tokens then sacking them for various effects. The wincons for this decks are vast; I continue to win games in new and surprising ways. Here's hoping someone else gets inspired to make something similar!

I'll lay out cards I feel I should or want to explain and their various purposes here:

Prossh, Skyraider of Kher: We want him for 3 reasons: His colors, his tokens, and his sac effect. After he resolves on the battlefield, he may as well be an enchantment that lets you sack for free. It's very easy for the tokens to get out of hand with this deck.

Token Generators:

Curse of Shallow Graves: It's not the best of cards, but you can attack with creatures you're going to sack anyway and get a bonus for it. This card doesn't tend to hurt you unless you're playing against a similar deck, and you enchant another player.

Tenacious Dead: I prefer this over Endless Cockroaches. I feel like I can control this card's place on the field better than I can the latter.

Jade Mage: Good to get early in the game, good to get late in the game. Pure value.

Skirsdag High Priest: A surprisingly good card in this deck. Very often you begin getting 5/5 demons every turn.

Korozda Guildmage: Potentially one I'll cut, this card is useful for token generation, though it's rare that you're in a position where you need more of it.

Sack Engines/Utilizers:

Disciple of Griselbrand: I personally like this card for it's ease of use and life gain abilities. You can gain a good bit of life with this dude, if you need to.

Shadowborn Demon: I prefer to play him when he forces me to sack creatures, not to mention the removal effect.

Corpse Traders: A very good find, this card is absolutely amazing.

Removal/Burn:

Burn at the Stake: Once again, a good find and an amazing card in this deck. It may as well read "Target player loses the game".

Gaze of Granite: My board wipe of choice; though this deck secretly fears board wipes like the plague (Prossh gets you back pretty quickly, while Golgari Charm is our only defense). Very good for wiping the board of threats under a certain CMC.

Purphoros: Necessary for every Prossh deck. With this deck, it's possible in turns 4-6 to deal lethal with this card.

Utility:

Obelisk of Urd, Muraganda Petroglyphs, and Conspiracy: I don't include Coat of Arms in this, as it benefits your opponents as well. considering nearly all of our tokens are vanilla, muraganda petroglyphs gives everything a hefty buff. Obelisk of Urd is very easy to cast, and will usually be used for Kobolds, as will Conspiracy.

The best part about this deck is finding things to use as tokens when you run out.
