This is an elemental based aggro deck.
These are the ideal 3 turn wins:
Scenario 1:
Turn 1: If you have Kiln Fiend in your hand then play any land card.
Turn 2: Play a second land card and play Kiln Fiend.
Turn 3: Use a combination of a double strike spell like Brute Force, a +3 attack spell like Titan's Strength and Distortion Strike or Artful Dodge to instantly 20-0 the enemy.
Scenario 2:
Turn 1: If you do not have Kiln Fiend in your hand but you do have Flamekin Harbinger, then play either Mountain or Steam Vents (or use the fetch land to get one) and play Flamekin Harbinger to put Kiln Fiend at the top of your deck.
Turn 2: Draw Kiln Fiend and then play another land to play it.
Turn 3: Use a combination of a double strike spell like Brute Force, a +3 attack spell like Titan's Strength and Distortion Strike or Artful Dodge to instantly 20-0 the enemy.
Scenario 3:
Turn 1: If you do not have either Kiln Fiend AND Flamekin Harbinger in your hand, but you have either phyrexian probe or Faithless Looting, then play either a Mountain or a Steam Vents (or use the fetch land to get one). Use the Gitaxian Probe to try to draw a Kiln Fiend or a Flamekin Harbinger. If you drew Flamekin Harbinger, then play it and put Kiln Fiend at the top of your deck.
Turn 2: If you used Flamekin Harbinger earlier, draw Kiln Fiend and then play another land to play it.
Turn 3: Use a combination of a double strike spell such as Assault Strobe, a +attack spell like Titan's Strength or Mutagenic Growth and an unblockable effect such as Artful Dodge to instantly 20-0 the enemy.
General Tips:
Use the HP effects on land cards, Mutagenic Growth, and Apostle's Blessing. Don't be afraid to take lots of self-damage.
Temur Battle Rage can be cast at instant speed, and so it can be useful to hold onto to bait the opponent into attacking.
Artful Dodge can be cast twice in the same turn for additional damage.
