I just came across the card Worldfire and just thought "Wow...I wanna light some stuff on fire."
THUS we have arrived at this deck.
The main combo comes from using card draw such as Faithless Looting to draw through your deck to get Worldfire and also discard another copy of Worldfire into your graveyard. Then by simply using a 1-cost spell such as Lightning Bolt or Flame Jab and having that card go into your graveyard along with Worldfire, you can then use Spellweaver Helix to imprint Worldfire and whatever the 1-cost card was.
Now comes the fun part:
Now lets say Spellweaver Helix is imprinted with Worldfire and Flame Jab. You can play another copy of Flame Jab, and by using Spellweaver Helix to cast Worldfire for free. By casting Rift Bolt the turn before, you can now deal 1 free damage at the start of your upkeep and win the game.
Best case scenario is a turn 3 win going something along the line of this:
Starting Hand: Worldfire, Mountain, Faithless Looting, Flame Jab, Mountain, Spellweaver Helix, Flame Jab
Turn 1: Draw a Rift Bolt, play a Mountain, tap 1 Mountain, play Faithless Looting, draw Worldfire and Forked Bolt, discard Worldfire and Flame Jab.
Turn 2: Draw a Pyretic Ritual, play a Mountain, tap 2 Mountains, play Pyretic Ritual, gain 3 red mana, play Spellweaver Helix and imprint Worldfire and Flame Jab to it.
Turn 3: Draw a Mountain, play a Mountain, tap 1 Mountain, play Rift Bolt for its suspend cost, tap 1 Mountain, play Flame Jab (target whatever you want to it really doesn't matter), this triggers Spellweaver Helix's ability and allows you to play Worldfire for no cost, setting the hp of your opponent to 1 and completely taking away their chances of victory by exiling all their permanents, their hand, and their graveyard. Keep in mind this all happens to you as well, but you have the Rift Bolt suspended, so you get to play it at the start of your upkeep next turn for no cost and win the game.
Pretty straightforward deck with technically a turn 4 win, but it's essentially a turn 3 win. Worst case scenario, it definitely should be over within 5 or 6 turns max.
