Overview:

This Prossh, Skyraider of Kher deck is a Jund aristocrats/combo build that leverages token generation, sacrifice synergies, and explosive mana to dominate through both combat and infinite loops. Prossh serves as the engine, generating Kobold tokens on cast to fuel sacrifice outlets like Goblin Bombardment, Phyrexian Altar, and Ashnod's Altar. The deck’s primary win conditions include direct damage via Purphoros, God of the Forge/Impact Tremors, infinite mana combos with Prossh + Altars, and overwhelming board states powered by Xenagos, God of Revels or City on Fire.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Prioritize ramp (Farseek, Nature's Lore, Cryptolith Rite) and token generators (Prossh casts). Deploy value engines like Elemental Bond or Morbid Opportunist.
2. Midgame Engine (Turns 4-6): Cast Prossh to create 6+ Kobolds (due to commander tax). Sacrifice tokens to Altars for mana or damage, or use them to power Mycoloth/Thromok the Insatiable. Activate Selvala, Heart of the Wilds with Prossh’s 5+ power for explosive mana.
3. Win Conditions:
   • Infinite Mana: Phyrexian Altar + Prossh (sacrifice Kobolds for mana, recast Prossh, repeat). Use infinite mana with Gluttonous Hellkite for a board wipe or Xenagos, the Reveler’s ultimate.
   • Direct Damage: Purphoros, God of the Forge + Prossh casts or Goblin Bombardment loops.
   • Overrun: Xenagos, God of Revels doubling Prossh’s power for lethal commander damage or City on Fire tripling damage output.

Mulligan Priorities:

• Keep hands with 2-3 lands (including color-fixing like Command Tower).
• Prioritize early ramp (e.g., Cryptolith Rite, Ruby, Daring Tracker) or a Prossh-enabling setup (e.g., Impact Tremors + a sac outlet).
• Avoid hands with no ramp or excessive high-CMC cards.

Key Tips:

• Use Hoarding Broodlord to tutor combo pieces like Phyrexian Altar or protection like Deflecting Swat.
• Skullclamp turns Kobolds into card advantage. Pair with Evolutionary Leap for creature filtering.
• Culling Ritual can wipe opponents’ early boards while accelerating your mana.

Weaknesses:

Critical

• Relies heavily on Prossh staying on the battlefield; repeated removal slows the deck significantly.
• No graveyard recursion for key combo pieces (e.g., Altars, Purphoros) beyond Eternal Witness-esque effects.

Moderate

• Vulnerable to Rest in Peace or Leyline of the Void, which disrupts Jarad, Golgari Lich Lord and recursion.
• Struggles against stax pieces like Torpor Orb (blocks ETB damage) or Cursed Totem (disables Selvala/Altars).

Minor

• Limited stack interaction (only Bolt Bend, Deflecting Swat).
• Mana base has several tapped lands, potentially slowing early plays.

Most Important Cards:

• Prossh, Skyraider of Kher (Token generation, combo enabler)
• Phyrexian Altar (Infinite mana combo, sac outlet)
• Purphoros, God of the Forge (Primary damage engine)
• Goblin Bombardment (Sac outlet, win condition)
• Xenagos, God of Revels (Combat finisher amplifier)
• Selvala, Heart of the Wilds (Mana acceleration)
• Hoarding Broodlord (Tutor for critical pieces)
• Cryptolith Rite (Mana generation from tokens)
• Culling Ritual (Board control + ramp)
• Impact Tremors (Secondary damage engine)

Attribute Ratings:

Speed: 7/10

• Can threaten infinite mana or lethal damage by turn 6-7 with optimal draws, but relies on resolving Prossh multiple times.

Resilience: 5/10

• Recovers poorly from repeated board wipes or commander tax, but has redundancy in sac outlets and card draw (e.g., Fecundity).

Consistency: 7/10

• Multiple tutors (Hoarding Broodlord, Finale of Devastation) and card draw engines ensure key pieces are accessible.

Interaction: 4/10

• Minimal removal beyond targeted spells like Deadly Rollick; focuses more on protecting its own strategy than disrupting opponents.

Rating Justification:

This deck has the speed to threaten wins by turn 6-7 through combos or combat, but its reliance on Prossh and vulnerability to disruption caps its resilience. It sits between optimized casual and focused competitive tiers, leveraging strong synergies but lacking the interaction and redundancy of higher-tier lists.

Power level: 6.0 - 6.5
