This deck capitalizes on the ability of Kiln Fiend. The goal of the deck is to create a one-turn instakilling, unstoppable, and protected creature, in an effort to win as soon as possible. The creature, Kiln Fiend, is buffed by a "Doubler" and "Unblocker," while being protected by a "Protecter" and facing less removal thanks to discard.
The Creature: [[Kiln Fiend]. In case you haven't noticed already, this creature gets +3/+0 whenever I cast an instant or sorcery. This is key for super-buffing it to be strong enough to finish the opponent in one turn. Flamekin Harbinger can tutor Kiln Fiend in.
Doublers: Assault Strobe and Tainted Strike. These spells both cut the amount of power needed to instakill the opponent in half. Tainted Strike has the extra bonus of providing its target +1/+0. So yeah, pretty self-explanatory.
Unblockers: Distortion Strike and Apostle's Blessing. The purpose of these spells are to make my creature unblockable, to ensure my opponent is the one to receive the fatal blow. These spells can be sideboarded out when facing a creatureless deck. Distortion Strike also gives +1/+0 for additional morbid splendor.
Protectors: Not of This World, Spellskite, and Apostle's Blessing. These cards protect my creature from removal and other anti-creature spells that can ruin my one chance to win. They are also obviously more useful vs. control and burn decks, so its a good idea to sideboard more in when facing them.
Discard: Duress and Inquisition of Kozilek Removes my opponent's removal or interrupts my opponent's early game, depending on their type of deck.
You can add Dizzy Spell to this deck if you're having consistency issues or are playing more casually.
Mwahahaha, and so now my creature is invincible, unstoppable, and ready to devastate the opponent with a single attack :D
Generic ComboKiln Fiend + Assault Strobe/Tainted Strike + Distortion Strike /Apostle's Blessing + any spare 1 mana instant. Not of This World/Spellskite's ability if needed. That's, at minimum, a 10 double strike unblockable. GG.
The sideboard on this deck is very important. Stubborn Denial is a great card to have as it gives this deck a lot of flexibility and is useful vs. control.
Mizzium Skin
is used as an additional counterspell, also useful vs. control. Spreading Seas,
Evil Presence
, and Sea's Claim is all burn hate. It royally screws any deck with a small manabase or dependent on a land like the Shrine to Nix (so it destroys nixwave as well).
Suggestions are welcome, HOWEVER I have pretty thoroughly thought out this deck and all its workings so it's probably as watertight as its going to get, but there might be a card I'm unaware of. Please don't suggest any of the following cards:
Gitaxian Probe I know its very powerful in this deck but there just isn't room, and with all the discard I think I'm going to have a sufficient understanding of my opponent's hand.
Mutagenic Growth I already kill the opponent easily with Kiln Fiend's ability, honestly this card does nothing
Lightning Bolt Same reason as above
Thoughseize
I would but too much money :x
Manamorphose/any other cantrip-- no room
Double Cleave
or
armed/dangerous
2 mana makes all the difference, I won't be able to fit all the different kinds of spells in
Thoughtseize I would but it's too expensive
This list will of course grow as more cards are suggested
