Overview:

This Jeskai (U/R/W) deck helmed by The Tenth Doctor and Rose Tyler focuses on time counter manipulation and suspend synergies. The strategy revolves around exiling cards with suspend via the Doctor's attack trigger, accelerating their arrival through time counter manipulation (e.g., Timecrafting, Jhoira's Timebug), and scaling Rose Tyler into a massive threat. Secondary themes include extra upkeep steps (Paradox Haze, Sphinx of the Second Sun) and value from casting spells from exile (Passionate Archaeologist). The deck aims to win via Rose Tyler commander damage, overwhelming suspended threats like Judoon Enforcers, or combo lines involving extra turns (Regenerations Restored, Teferi, Master of Time).

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Deploy mana rocks (Sol Ring, Arcane Signet), suspend high-impact cards (Ancestral Vision, Lotus Bloom), and cast commanders. Use The Reality Chip or Archivist to maintain card flow.
2. Time Counter Acceleration (Turns 3-6): Activate The Tenth Doctor’s "Timey-Wimey" ability with surplus mana, use Timecrafting to remove counters from suspended cards, and trigger Rose Tyler’s growth. Deploy Paradox Haze or Sphinx of the Second Sun for multiple upkeeps.
3. Win Conditions (Turns 6+):
   • Combat: Attack with Rose Tyler (often 10+/10+ by this stage) using Whispersilk Cloak for evasion.
   • Suspended Threats: Resolve Inevitable Betrayal or Dinosaurs on a Spaceship for board dominance.
   • Combos: Regenerations Restored + time counter removal for extra turns; Teferi, Master of Time’s ultimate for infinite turns.

Mulligan Priorities:

• Prioritize hands with 3 lands, 1-2 ramp pieces, and at least one suspend card or time counter manipulator.
• Keep hands with Paradox Haze or As Foretold if early mana is secure.
• Avoid hands with only high-CMC suspend cards lacking acceleration.

Key Tips:

• Use Wibbly-wobbly, Timey-wimey to reset key suspended cards or accelerate Rose Tyler.
• Jhoira of the Ghitu can suspend noncreature bombs like Farewell for explosive late-game turns.
• Protect Rose Tyler with Lightning Greaves to ensure her growth isn’t interrupted.

Weaknesses:

Critical

• Graveyard Reliance: Recursion like Hourglass of the Lost and Epochrasite is neutered by common graveyard hate (Rest in Peace).
• Suspend Disruption: Drannith Magistrate or Uba Mask shut down casting from exile, crippling the primary strategy.

Moderate

• Artifact/Enchantment Reliance: Key pieces like Paradox Haze and As Foretold are vulnerable to removal.
• Slow Setup: Suspend-heavy lines take 3+ turns to pay off, giving opponents time to react.

Minor

• Limited Board Wipes: Only Farewell and Time Wipe for resetting; struggles against wide boards early.

Most Important Cards:

• Paradox Haze (Doubles upkeep triggers for faster suspends)
• Teferi, Master of Time (Instant-speed activations, extra turns)
• Jhoira of the Ghitu (Suspend any card for delayed value)
• Rose Tyler (Primary win condition via scaling power)
• As Foretold (Free casts from hand as time counters accrue)
• Regenerations Restored (Extra turns enabler)
• The Reality Chip (Ensures land drops and casts from top)
• Timecrafting (Critical time counter manipulation)
• Inevitable Betrayal (Steal opponents’ threats)
• Sphinx of the Second Sun (Doubles upkeeps/triggers)

Attribute Ratings:

Speed: 5/10

• Suspended win conditions typically resolve around T7-9, though combo lines with Teferi or Regenerations Restored can accelerate this.

Resilience: 5/10

• Limited protection outside Everybody Lives!; key enchantments/artifacts are fragile, but some recursion (Hourglass of the Lost) exists.

Consistency: 6/10

• Moderate card draw and tutors (Personal Tutor, The Reality Chip), but relies heavily on drawing time counter synergies.

Interaction: 5/10

• Spot removal (Path to Exile, Swords to Plowshares) and counterspells (Unwind), but lacks stack control for combo disruption.

Rating Justification:

This deck has a focused game plan with multiple avenues to victory but operates at a slower, telegraphed pace typical of casual tables. Its combo potential and commander synergy push it above precons, but inconsistent protection and reliance on delayed triggers cap its power.

Power level: 5.0 - 5.5
