UPDATE Changes to the deck as of 11/1:

Cut 4 Polluted Delta, 4 Dark Ritual, 2 Cruel Bargain , and 2 Infernal Contract for 4 Forbidden Orchard, 4 Spoils of the Vault, 1 Ornithopter, 1 Crimson Kobolds , 1 Shield Sphere , and 1 Memnite. Forbidden Orchard helps with Slaughter Pact. The draw engine is redundant, spoils is another 1 card combo, and the 0-drops enable Slaughter Pact and Pact of Negation to have legal targets so they're not dead cards. The choice of 0-drops was purely aesthetic. This deck now has a win-con game 1 in the form of Memnite. The winning strategy in all subsequent games is to side in Storm Crow.

Do you hate long games of Magic? Have you ever wanted to play a game of Magic so fast that your opponent won't even know what hit them? Then I have the deck for you. This deck is guaranteed to end the game quickly (except you might lose). Allow me to explain the combo pieces:

Here are just some of the many game-ending combos:

Turn 1 Summoner's Pact, fail to find, fail to pay upkeep cost next turn.

Turn 1 Pact of the Titan , put a 4/4 token into play, fail to pay upkeep cost next turn.

Turn 1 Intervention Pact, fail to pay upkeep cost next turn.

If you want to deny your opponent the opportunity to play Magic and you are on the play, then here's the solution:

Turn 1 Land, Lotus Petal, cast Final Fortune , Last Chance , or Warrior's Oath . Take the extra turn.

These 2 routes will end the game without any decision-making on the part of your opponent. This means that, together with Serum Powder, the probability of "goldfishing" a turn 1 game-ending opening hand using either of these 2 routes would be VERY close to 100%. Seriously, try playtesting the deck. If you can't combo off, try to mulligan or use Serum Powder. I guarantee you that the game will not go past turn 2.

BTW, if anyone can figure out the actual probability of getting the combo pieces goldfishing (not Pact of Negation or Slaughter Pact as they require a target and would require decision making on the part of your opponent) that would be amazing. I tried, but the math is just way too complicated. This deck is that good.
