MTG Salvation

Hmm.

Okay.

bazaar. Discard Golgari Grave Troll, dragon shadow, dragon scales. 6 cih
Cycle Street Wraith, dredge Troll (5 unknown cih)
Reveal Scourge Devil, Extractor Demon, the other three Dragon enhantments, and ???
Exile five spirit guides to unearth both creatures, put a bunch of enchantments on them

Drat.
Ok.

Guide guide guide myr lotus.
Aether spell bomb, bounce blue Iona, U floating.
Ancestral
Pact of Negation on silence.
Draw back up to three.
Main phase, Mox Sapphire, Mana Crypt, Time Twister
7 cards in hand, blue spells available to cast, Black Lotus shuffled back in. Easy to win from here

Quote from BronYAur

Well, Shimmer Myr with 3 ESG is good.
Then:

Black Lotus for 3 blue
Aether Spellbomb, activate it to bounce the blue-naming Emeria
Pact of Negation on Silence

Draw phase, you still have one blue and you draw, uhm, Ancestral Recall.
Cast it, draw 3.

Noiw you are free to play blue, colorless, land, no X and no over 3cc. Shouldn't be hard, even if Lotus is gone...

As pointed out, doesn't work; can't keep the mana floating.

However:

3x spirit guide, Shimmer Myr, Black Lotus, LED.
Use Lotus to Pay for Ichor Wellspring, crack LED in response
Draw from Wellspring, 4 mana floating
Krark Clan Ironworks
Sac wellspring, draw. Cast another wellspring, sacrifice, repeat x3 (4 cih, 2 mana)
Chromatic Star x 4, Terrarion x 4 (4 CIH, 9 mana)
Duplicant eats White Iona
Sacrifice Duplicant
Mox Pearl
Lotus Petal
Second Sunrise
etc....

You control no Mountain, so Anger isn't giving your guys haste

Exile Elven Spirit Guide end step
Tap Glimmervoid, Cycle Undead Gladiator 6 CIH
Upkeep, exile Simian Spirit Guide (5 CIH), return Gladiator to hand, discard Golgari Grave Troll (4 card + gladiator)
Dredge 6 cards including Anger, 4x Narcomeba, Scourge Devil. (4 cards, Troll in hand)
Play Mountain, exile two spirit guide and tap mountain, Unearth Scourge Devil.
Attack, using last two cards for Spirit Guide/Rubblebelt Maka

Total damage = 15.

Modern legal is even simpler
Leyline of the Meek x3
Chancellor of the Forge x4

Kills t2.

Cavern of Souls
Leyline of Vitality
Xantid Swarm
Simian Spirit Guide
Shinen of Fury's Fire
Black Lotus
Ancestral Recall

Top of deck: Flash, Proteus Hulk, Island, Island, (Proteus hulk kill package)

t1 kill, play or draw.

Simian Spirit Guide
Forest
Cavern of Souls
Thalia, Guardian of Thraben
Blazing Shoal
Progenitus
Berserk

Top card: Simian Spirit Guide

kills turn 2 even on the play. Thalia shuts off the entire opponent deck; Berserk tramples for lethal over the chump-blocking Ornithopter, with Cavern and a Spirit Guide to pay the extra cost Thalia imposes. This deck is ALMOST modern legal, but I can't find a suitable replacement for Berserk.

Leyline of Life Force
Ancient Tomb
Simian Spirit Guide x 2
Barbed Shocker
Island
Omniscience

Top of deck=edit: Show and Tell Release the Ants, Emrakul

t2 kill. Legacy legal. Turn 1, discard opponents hand; turn 2, show and tell Omniscience, draw Release the ants, cast it for infinity damage.

Quote from Mogg

Inferno wins immediately.

It draws. YOu're at 4 life, so you take 1 from Ember Hauler and 3 from inferno bringing you to 0.

Quote from Feyd_Ruin

Draw your god card that allows you to survive this turn and swing a win next turn.

God card, or god draw?

Cause Scout's Warning into Wurmcoil Engine blocking blocking Wort oughta do it, but that requires the top of your deck to be stacked perfectly.

Edit: looks like the correct answer doesn't require such shenanigans.
