Overview:

This Jeskai (WUR) artifact-energy deck helmed by Immard, the Stormcleaver focuses on generating and proliferating energy counters to fuel explosive combos, value engines, and alternate win conditions. The strategy leverages high-powered artifacts like Urza, Lord High Artificer, Tezzeret the Seeker, and Aetherworks Marvel to create mana advantage and cheat out game-ending threats. Immard serves primarily as a flexible removal/protection tool rather than the deck's core, with key "hidden commanders" like Daretti, Scrap Savant and Saheeli, Sublime Artificer driving artifact recursion and token generation. The deck employs multiple infinite combos and can pivot between storm-like turns, extra combat phases via Lightning Runner, and overwhelming board states.

Primer:

Core Strategy Execution:

1. Energy Acceleration (Turns 1-4): Deploy energy generators like Conversion Apparatus, Assaultron Dominator, and Dr. Madison Li alongside fast mana (Mox Opal, Mana Vault). Use proliferate engines like Flux Channeler and Tekuthal, Inquiry Dominus to amplify counters.
2. Artifact Synergy Setup (Turns 3-5): Resolve key value pieces - Urza, Lord High Artificer for mana/card advantage, The Reality Chip for top-deck manipulation, and Norn's Choirmaster to turbo-charge proliferate triggers. Tutor combo components with Whir of Invention or Enlightened Tutor.
3. Win Condition Execution (Turns 4-7):
   • Infinite Mana/Storm: Isochron Scepter imprinted with Dramatic Reversal + 3+ mana rocks enables infinite untaps. Pair with Staff of Compleation for infinite proliferate/damage or Aetherworks Marvel to cast the entire deck.
   • Extra Turns: Gonti's Aether Heart provides game-ending extra turns when fueled by energy from Izzet Generatorium or Sphinx of the Revelation.
   • Combat Overkill: Liberty Prime, Recharged and Craterhoof Behemoth-style effects via Nettlecyst and token armies from Saheeli, Sublime Artificer.

Mulligan Priorities:

• Keep hands with 2-3 lands including artifact lands (Ancient Den, Great Furnace).
• Prioritize early energy generators (Solar Transformer, Bespoke Battlewagon) or fast mana (Sol Ring, Grim Monolith).
• Look for at least one tutor (Enlightened Tutor, Mystical Tutor) or card advantage engine (Rhystic Study, The One Ring).
• Hands with protection (Teferi's Protection, Deflecting Swat) are preferred against interaction-heavy metas.

Key Tips:

• Use Displacer Kitten to reset planeswalkers/ETB creatures while dodging removal.
• Urza's Saga fetches critical 0-1 CMC artifacts like Mox Opal or Esper Sentinel.
• Staff of Compleation serves as a Swiss Army knife - use its proliferate ability with Tekuthal for quadruple counters.
• Scrap Mastery acts as both a board wipe and reanimation spell for your artifacts.

Weaknesses:

Critical

• Artifact Board Wipes: Vandalblast or Null Rod effects cripple 80% of the deck's strategy.
• Counterplay to Energy: Vorinclex, Monstrous Raider/Solemnity nullifies energy accumulation and proliferate triggers.
• Stack Interaction: Lacks protection against Defense Grid or Overcharged Amalgam disrupting critical combo turns.

Moderate

• Graveyard Hate: Rest in Peace disrupts Daretti, Scrap Savant and Scrap Mastery recursion.
• Tax Effects: Thalia, Guardian of Thraben slows the deck's low-to-the-ground artifact synergies.

Minor

• Aggressive Decks: Struggles against hyper-fast combat strategies pre-T5 without Blasphemous Act.
• Color-Specific Hate: Stony Silence is less prevalent than general artifact hate in most metas.

Most Important Cards:

• Urza, Lord High Artificer (Mana engine/win condition)
• Isochron Scepter + Dramatic Reversal (Infinite untap combo)
• Gonti's Aether Heart (Extra turn generator)
• Tekuthal, Inquiry Dominus (Proliferate amplifier)
• Whir of Invention (Tutor for combo pieces)
• The One Ring (Card advantage/protection)
• Mana Vault (Explosive ramp)
• Staff of Compleation (Swiss Army knife value engine)
• Force of Will (Free interaction)
• Tezzeret the Seeker (Artifact tutor/board threat)

Attribute Ratings:

Speed: 8/10

• Capable of T3-4 wins with perfect hands (Scepter+Reversal+rocks), typically threatening wins by T5-6 through multiple redundant combo lines.

Resilience: 7/10

• Robust protection suite (Teferi's Protection, free counterspells) and artifact recursion (Daretti, Scrap Savant, Academy Ruins) mitigate disruption, but core combos remain vulnerable to instant-speed artifact removal.

Consistency: 9/10

• 14 tutors, 10+ card draw engines, and multiple overlapping combo lines ensure reliable access to win conditions.

Interaction: 8/10

• Premium counterspells (Force of Negation, Mana Drain), targeted removal (Swords to Plowshares), and board wipes (Cyclonic Rift) provide comprehensive answers.

Rating Justification:

This deck operates at cEDH-adjacent speeds with T3-4 win potential through efficient combos and free interaction, but lacks the deterministic T1-2 lines and compact win conditions of top-tier lists. Its artifact dependency and vulnerability to widespread hate keep it just below true cEDH viability despite high power.

Power level: 8.0 - 8.5
