Overview:

This Obeka, Splitter of Seconds deck leverages "end of turn" effects and multiple upkeep triggers to generate overwhelming value and win through combat damage, monarch pressure, and artifact-based alt-conditions. Obeka herself is the critical engine, enabling extra upkeep steps via combat damage to amplify enchantments like the Court cycle (Court of Ire, Court of Ambition, etc.), Thopter Spy Network, and suspend payoffs. The deck protects Obeka with evasion equipment (Silver Shroud Costume, Rogue's Passage) and recursion (Supernatural Stamina, Undying Evil), while using copy effects (Mirrormade, Copy Enchantment) to multiply upkeep triggers. Win conditions include Obeka commander damage, Court life drain, Mechanized Production, and wide boards enabled by Court of Embereth/Goblin Assault.

Primer:

Core Strategy Execution:

1. Setup (Turns 1-4): Deploy mana rocks (Sol Ring, Talismans), protection for Obeka (Swiftfoot Boots, Champion's Helm), and early value pieces like Propaganda or Nightscape Familiar. Prioritize lands enabling turn 4 Obeka.
2. Commander Deployment & Evasion (Turns 4-5): Cast Obeka. Equip immediately with evasion tools (Silver Shroud Costume, Winged Boots, Robe of the Archmagi) to guarantee combat damage. Use Access Tunnel or Enter the Enigma if needed.
3. Amplify Triggers (Turns 5+):
   • Resolve Obeka's combat damage to gain extra upkeeps.
   • Play upkeep-centric permanents: Courts, Paradox Haze, Sphinx of the Second Sun, Extravagant Replication. Copy key enchantments for exponential triggers.
   • Suspend high-impact spells (Ancestral Vision, Rousing Refrain) or cheat permanents with Jhoira of the Ghitu.
4. Win Condition Execution:
   • Combat: Swing with unblockable Obeka (commander damage) or wide boards buffed by Rising of the Day/Bulk Up. Temur Battle Rage enables lethal surprise damage.
   • Upkeep Drain: Leverage Court of Ambition life loss/discard and Court of Ire targeted burn.
   • Artifact Alt-Win: Flood the board with Thopters (Thopter Spy Network) or copied artifacts (Extravagant Replication), then win via Mechanized Production.

Mulligan Priorities:

• Keep hands with 3+ lands (including U/B/R sources) and 2-3 mana accelerants (rocks, dorks).
• Prioritize Obeka protection/evasion (Boots, Shroud Costume, Rogue's Passage) or an early Court/Paradox Haze.
• Suspend payoffs (Ancestral Vision) or card draw (Relic of Sauron) are strong supplements.
• Avoid hands lacking early ramp or without a clear path to connect Obeka.

Key Tips:

• Sequence Evasion First: Equip Obeka before attacking to ensure she connects. Silver Shroud Costume's flash enables surprise blocks/removal dodging.
• Double Upkeep Triggers: Strionic Resonator copies Obeka's combat damage trigger, granting 2x extra upkeeps per hit.
• Protect Critical Engines: Use Kaya's Ghostform/Supernatural Stamina on Obeka or key pieces like Sphinx of the Second Sun.
• Leverage End-of-Turn: Cast "end of turn" effects (Undying Evil, Artful Dodge) before Obeka's ability resolves to avoid downsides.

Weaknesses:

Critical

• Commander-Centric Vulnerability: The deck collapses if Obeka is repeatedly removed or unable to connect. Limited protection beyond equipment makes this a severe risk.
• Enchantment/Artifact Hate: Farewell, Austere Command, or targeted removal cripples the Court engines, replication effects, and Mechanized Production win.

Moderate

• Board Wipe Recovery: Lacks mass recursion; recovering from Blasphemous Act/Toxic Deluge is slow outside Obeka recursion.
• Stack Interaction Gaps: Minimal counterspells (only Negate) struggle against noncreature combos or game-winning sorceries.

Minor

• Graveyard Reliance: Recursion spells (Undying Evil, Supernatural Stamina) are weak to Rest in Peace effects.
• Mana Constraints: High-CMC cards (Sphinx, River's Rebuke) can stall the deck if ramp is disrupted early.

Most Important Cards:

• Paradox Haze (Doubles upkeep triggers for Obeka/Courts)
• Silver Shroud Costume (Guarantees Obeka evasion & protection)
• Court of Ambition (Primary life-drain win condition)
• Strionic Resonator (Copies Obeka's trigger for extra upkeeps)
• Extravagant Replication (Generates exponential artifact/creature tokens)
• Mechanized Production (Alt-win condition with artifact tokens)
• Swiftfoot Boots (Critical haste & hexproof for Obeka)
• Sphinx of the Second Sun (Provides extra phases to compound upkeep value)
• Robe of the Archmagi (Draws cards on Obeka damage & enables evasion)
• Jhoira of the Ghitu (Cheats high-impact permanents via suspend)

Attribute Ratings:

Speed: 6/10

• Can threaten wins via commander damage or Court drain by turn 7-8, but relies heavily on setup turns and Obeka connecting.

Resilience: 5/10

• Recursion protects Obeka, but the strategy folds to repeated removal or enchantment wipes. Limited answers to stack threats.

Consistency: 6/10

• Strong card draw (Robe, Courts) and replication effects find pieces, but lacks tutors for specific win conditions.

Interaction: 5/10

• Targeted removal (Terminate, Infernal Grasp) and board wipes are solid, but minimal stack interaction leaves combo vulnerabilities.

Rating Justification:

The deck executes a focused game plan around multiple upkeep triggers enabled by Obeka, threatening wins via combat, drain, or alt-conditions around turn 7-8. However, its commander dependency and vulnerability to disruption cap its resilience, placing it below optimized tiers.

Power level: 6.0 - 6.5
