Overview:

This Jeskai (WUR) deck leverages The Tenth Doctor and Clara Oswald to manipulate time counters and suspend mechanics, aiming to cheat high-impact spells into play while generating value through triggered ability duplication. The core strategy revolves around exiling cards with suspend via the Doctor's attack trigger, accelerating their arrival through time counter manipulation (Clockspinning, Wibbly-wobbly, Timey-wimey), and winning through either infinite turns (Time Warp + recursion), combo finishes (Thassa's Oracle/Laboratory Maniac with forced deck-out), or overwhelming value from extra turns and suspended bombs like Ulamog, the Ceaseless Hunger. Clara Oswald doubles triggered abilities, amplifying both suspend-related triggers and planeswalker activations.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4):
   • Deploy mana rocks (Sol Ring, Mox Tantalite, Basalt Monolith) and value engines (Rhystic Study, Smothering Tithe).
   • Cast The Tenth Doctor early to begin exiling suspend targets. Use As Foretold to cast suspended spells for free as counters accumulate.
   • Protect key pieces with Teferi's Protection and Force of Will.

2. Mid-Game Acceleration (Turns 4-7):

   • Activate The Tenth Doctor's "Timey-Wimey" ability to manipulate counters on suspended cards and permanents like The Millennium Calendar.
   • Deploy combo enablers: Isochron Scepter imprinted with Dramatic Reversal (with sufficient rocks for infinite mana) or Clockspinning for counter manipulation.
   • Use tutors (Mystical Tutor, Tezzeret the Seeker) to find win conditions or Omniscience.

3. Win Condition Execution:

   • Infinite Turns: Loop Time Warp via Mystic Sanctuary recursion or Narset, Enlightened Master casts.
   • Thoracle/Lab Maniac: Draw the deck via The One Ring/Alhammarret's Archive with infinite mana or Consecrated Sphinx.
   • Millennium Calendar: Activate The Millennium Calendar’s 1,000-counter lethal trigger using Clockspinning and Rotating Fireplace.

Mulligan Priorities:

• Keep hands with 2-3 lands, preferably including Command Tower or tri-lands.
• Prioritize early ramp (Sol Ring, Isochron Scepter) or card advantage (Rhystic Study).
• Ensure at least one interaction piece (Cyclonic Rift, Force of Will) if facing aggressive metas.

Key Tips:

• Use Gandalf the Grey to copy extra turn spells or Teferi's Protection for protection.
• The War Doctor scales with phased-out permanents (e.g., via Gallifrey Falls // No More), enabling lethal commander damage.
• Wibbly-wobbly, Timey-wimey synergizes with suspended cards and The Millennium Calendar for rapid counter accumulation.

Weaknesses:

Critical

• Artifact/Enchantment Reliance: Isochron Scepter, Smothering Tithe, and As Foretold are vulnerable to mass removal (Farewell).
• Suspend Disruption: Drannith Magistrate or Uba Mask nullifies suspend strategies.
• Graveyard Dependency: Mystic Sanctuary recursion and Laboratory Maniac are foiled by Rest in Peace.

Moderate

• Slow Setup: Suspend delays and high-CMC win conditions (Omniscience, Time Stretch) struggle against fast combo decks.
• Mana Base Fragility: Overreliance on nonbasic lands (tri-lands, Temple cycle) makes the deck susceptible to Blood Moon.

Minor

• Limited board presence early; struggles against wide aggro without Propaganda or Cyclonic Rift.

Most Important Cards:

• Isochron Scepter (Infinite mana/combo enabler)
• Thassa's Oracle (Primary win condition)
• Dramatic Reversal (Combo piece with Scepter)
• The Tenth Doctor (Suspend engine)
• Teferi's Protection (Board protection)
• Mystical Tutor (Tutor for combo/answers)
• Smothering Tithe (Mana acceleration)
• The One Ring (Card draw engine)
• Cyclonic Rift (Board reset)
• As Foretold (Free spell casting)

Attribute Ratings:

Speed: 7/10

• Capable of T4-6 wins with ideal draws (Scepter + Reversal + payoff), but suspend delays and high-CMC spells slow average games.

Resilience: 5/10

• Limited protection beyond counterspells and Teferi's Protection; combos are fragile to targeted removal.

Consistency: 6/10

• Moderate tutor density and card draw, but lacks redundancy for key combo pieces like Isochron Scepter.

Interaction: 7/10

• Strong stack interaction (Force of Will, Mana Drain) and board wipes (Farewell), but minimal creature removal.

Rating Justification:

This deck has high potential speed (T4-6 wins) via compact combos and extra turns but suffers from susceptibility to artifact/enchantment removal and inconsistent access to its primary win conditions. Its resilience and interaction suite place it in the Focused Competitive tier, aligning with T5-6 win benchmarks.

Power level: 6.5 - 7.0
