This is a deck I whipped up for Origins Standard. By using small, efficient creatures and lots of burn spells, your opponent is dead before they know what happened. [Avaricious Dragon is a placeholder for Scab-Clan Berserker]
The Decklist:
CREATURES:
Chandra, Fire of Kaladesh - This powerhouse can deal small burn as a creature, but when she flips she relentlessly reduces your opponent's life total and eliminates small creatures
Monastery Swiftspear - This great creature hits immediately, and gets bigger the more you burn your opponents
Zurgo Bellstriker - A 2/2 for one who hits big early on can pose an early threat
Goblin Rabblemaster - Taking advantage of the Goblin subtheme of the deck, this bomb brings a massive threat to the table each turn
Scab-Clan Berserker - Make this hasty beater a utility creature that punishes almost any archetype with removal, counter spells, burn, or any noncreature spells
Abbot of Keral Keep - This threat can swing and get bigger for more damage, plus it gives you a free card late game
INSTANTS:
Lightning Strike - The basis of burn
Wild Slash - Quick burn, pretty basic (a small Strike)
Atarka's Command - Burn, mass pump, an extra land, or no life gain? Cool with me
Stoke the Flames - A possible 4 damage at Instant speed for no mana? What else does life require?
Titan's Strength - One mana for a large pump and a Scry 1 is very good quality in this deck
Fiery Impulse - In this deck, this card is a Lightning Bolt for creatures only, which is just fine with me
SORCERIES:
Exquisite Firecraft - Like Fiery Impulse, this is always a 3-mana 4 uncounterable damage
Hordeling Outburst - Three attackers/blockers that can chump block for days (plus that Goblin theme)
Dragon Fodder - This is a smaller Outburst, so we know this is fine
LANDS:
Red Aggro splashing for the Command; we use lots of Mountains, some Forests, and some Foothills to fix
SIDEBOARD:
Shaman of the Great Hunt - Comes in against Control to push damage faster
Smash to Smithereens - That U/R Artifact deck with Thopters everywhere? Kill their threats and deal extra damage
Back to Nature - I have a feeling an Enchantment deck will go around
Roast - Midrange. Enough said
Rending Volley - That White Weenie deck that is highly anticipated? U/W Control? This is great in several matchups.
Thunderbreak Regent - Any deck with removal or large fliers can have this come in
Hope you enjoy this deck! Feedback appreciated!
