A while ago I tried making a budget turn one win deck, and Ad Nauseam was the best card I could find for doing so. This is the new and improved version of the deck, which still revolves around casting Ad Nauseam as fast as possible.Card breakdown:Ad Nauseam : Casting this basically means you win. Though you won't draw out your entire deck using this card you'll draw most of it, then you can cast a bunch of 0 mana creatures and win.
Grapeshot : This is the kill card in the deck. Other options include Tendrils of Agony and Carrion Feeder but Carrion Feeder is weak and Tendrils of Agony makes you lose a lot of life when you use Ad Nauseam to draw it.
Crimson Kobold, Crookshank Kobolds, Phyrexian Walker, Ornithopter : These are the most budget 0 mana creatures I could find. They fuel Culling of the Weak and they don't make you lose any life when you cast Ad Nauseam.
Dark Ritual, Culling of the Weak : These are huge mana engines that help you cast Ad Nauseam as soon as possible.
Lotus Petal : Another free mana source that doesn't make you lose life when you draw it using Ad Nauseam. Perfect.
Paradise Mantle, Jeweled Amulet The ability to store mana is very helpful for a turn 2/3 win in the deck.
Spellbook : This card is very helpful if you have to stop drawing cards using Ad Nauseam and you need to pass the turn. By keeping your 0 mana spells you can save the storm count for the next turn or the turn after.
Zuran Orb : After you tapped your mana you won't need it, this card will let you Ad Nauseam further and also gain life afterward if you didn't cast Grapeshot yet.
Viscera Seer : Possibly one of the most underrated commons in magic, this card lets you scry after casting Ad Nauseam. You can draw the cards you scry using cycling lands.
Polluted Mire, Barren Moor : At 0 mana cost these guys let you draw cards after casting Ad Nauseam and are extremely helpful. You can also cycle them early in the game.
Swamp Almost all black decks have at least 1 copy of this card, so I included 10. In this deck is generally better than Peat Bog which didn't perform very well in testing.
How to play this deck:Think hard about your mulligans. If you don't have an Ad Nauseam mulliganning is usually the best option. This deck can go off even with very few mana sources in your hand, assuming you draw more quickly. Once you cast Ad Nauseam just keep drawing cards until the life you lost brings your life total to 5 or less. Don't draw cards beyond this point because you risk losing to putting another Ad Nauseam in your hand and losing the game. You can continue drawing and trust your luck if you want. Also stop if you drew Grapeshot and you have enough storm to win the game. If you don't have Grapeshot in your hand play Viscera Seer/[[Spellbook] and then start sacrificing creatures to scry. Once Grapeshot is on top, or you ran out of creatures to sacrifice use your cycling lands (and extra mana from Dark Rituals you drew). In the extremely unlikely situation that you still haven't found Grapeshot you can try to survive using Spellbook. Remember that the storm count only works for spells you cast that turn.Less Budget options include Chrome Mox, Mox Diamond and slightly more expensive 0 mana creatures like Shield Sphere. Also Diabolic Intent and Burning Wish to tutor tendrils of agony from the sideboard. Phyrexian Tower is another powerful land that can be used in a non-budget deck.
