Final version of my Red/Blue Sneaky Aggro deck, which I decided to name Kiln Distortion (to help point out the main combo)
---Creatures---
The Core creatures here are Kiln Fiends. Kiln Fiend gets super powerful from your cheap little spells while. Goblin Guide is there for a power 1 mana cost creature drop. Plated Geopede is there to help put the pressure on, being a 5/5 on turn 3 if you play a fetch land. Ruinous Minotaur can help be a win-con in this deck. Hurts yourself, but can really help deal damage, if you make it unblockable (or using Smoldering Spires). Another "Enchanted" Creature is Wind Zendikon. It's a 2/2 flyer that uses 1 land as a body. It's just awesome for this deck, lets you attack with a 2/2 flyer on turn 2 for only 1 blue mana. Also has great Synergy with Ruinous Minotaur (explained in Combo section)
---Land---
Basically, you keep it about 20 lands if you want to keep the quickness, 22 for Standard, and 24 for longer games. I'm at 22 for balance. Plenty of fetch lands for pumping Plated Geopede and a few Smoldering Spires for land-based attempts at a free hit.
---Spells---
You got your standard burn spells, Lightning Bolt for player and Flame Slash for creatures. Nothing to see here. Staggershock is the same, but it's rebound ability really helps, does 4 damage for 3 mana, dividable by 2. Like a super forked bolt. It's rebound also helps keep my critters pumped up. Spell Pierce - basically, this deck should never get past turn 5. That's why Spell Pierce is here, to be an excellent low cost counter, helping protect my Kiln Fiends. Most of the time, they wont have an additional 2 mana to stop the counter. Distortion Strike is the very idea of the deck, use it on Kiln Fiend to make it a 5/2 unblockable for 2 turns, or put on a Plated Geopede, then use Scalding Tarn to hit for 6, or use it on Ruinous Minotaur as a easy way to hit for 6 damage. Ponder is there to help plan out your moves and have slight card advantage.
---Combos---
Obviously, combo #1 is Kiln Fiend with a Distortion Strike. Very deadly move. Another type of combo would be Plated Geopede with Scalding Tarn, swing for 5/5 first strike on T3. Then we have Ruinous Minotaur + Wind Zendikon + Distortion Strike. Put DS on Ruinous Minotaur, then attack with him and Wind Zendikon, then after damage, sac Wind Zendikon to save a land.
---Sideboard---
1) Manabarbs. Eat apart stalling U/W Control Decks.
2) Into the Roil. Bounce back planeswalkers or
expensive artifacts/enchantments.
3) Swerve - redirect spot removal.
4) Shatter. Anti Artifact spell.
5) Unstable Footing. Bonus to Kiln fiend + eliminates damage preventions and protection, like Kor Firewalkers.
PERFECT PLAY
Turn 1 - Mountain, Goblin Guide, attack (18)
Turn 2 - Island, Kiln Fiend, Goblin attack (16)
Turn 3 - Mountan, Distortion Strike, 2x Lighting Bolt life (6 damage), Kiln Fiend attacks for 12/2 unblockable, Goblin attacks (-4)
Yeah, it can kill THAT fast.
