IzzetLegendary Creature — Time Lord DoctorThe Fifteenth Doctor
Mana value4Rank#15,134
The Commander
Whenever The Fifteenth Doctor enters or attacks, mill three cards. You may put an artifact card with mana value 2 or 3 from among them into your hand.
The first nonartifact spell you cast each turn has improvise. (Your artifacts can help cast that spell. Each artifact you tap after you're done activating mana abilities pays for 
.)
Guide
Gameplan
Use The Fifteenth Doctor to mill into and recur cheap artifacts, then use those artifacts (via improvise) to power out big spells each turn. You build a board of artifacts and mana rocks, attack to dig deeper, and convert that artifact mass into either huge X-spells, cost-reduced threats, or an explosive combo turn. The deck plays like a tempo-artifact engine that snowballs as your artifact count grows.
Strengths
- Free card advantage and selection on every attack and re-cast keeps the engine churning.
- Improvise turns lands-light hands into explosive turns, letting you cast oversized spells early.
- Deep UR artifact synergies (cost reducers, treasure, mana rocks) are well-supported and cheap.
- Self-mill enables graveyard recursion subthemes for artifacts and instants/sorceries.
Weaknesses
- Improvise only helps the first nonartifact spell each turn, limiting nut-draw ceilings.
- Artifact-heavy boards are vulnerable to mass artifact removal (Vandalblast, Bane of Progress).
- UR lacks reliable lifegain and struggles against fast aggro and aristocrat drains.
- Self-mill can deck you or bin key pieces without recursion or graveyard hate protection.
- Commander is fragile at 4 toughness and dies to most spot removal, slowing the engine.
Key Cards
- Urza, Lord High Artificer — Turns your artifacts into mana and provides a powerful artifact-driven engine that pairs perfectly with improvise.
- Sai, Master Thopterist — Draws cards as you flood the board with artifacts and provides bodies for both improvise fuel and defense.
- Whir of Invention — Improvise tutor that grabs your best artifact while The Doctor discounts other spells, finding combo or value pieces.
- Goblin Engineer — Recurs key artifacts from the graveyard the Doctor mills, smoothing your self-mill into card advantage.
- Reckless Fireweaver — Converts every artifact entering play into direct damage, a strong incremental win path in an artifact-dense deck.
- Mystic Forge — Lets you cast artifacts off the top, turning self-mill and a deck full of rocks into a draw engine.
Upgrade Path
Add fast mana rocks (Mana Crypt, Mana Vault, Sol Ring) and cost reducers to maximize improvise turns, then layer in tutors like Whir of Invention and Gamble to find combo pieces. Build toward an Urza/Sai mana engine plus a payoff such as Reckless Fireweaver or a big X-spell to close fast. Round out with protection (Swan Song, Dispel) and graveyard recursion (Goblin Welder) so self-mill becomes pure advantage.

Win Conditions
- ▸Artifact ETB pingers like Reckless Fireweaver or Marionette Master draining the table.

- ▸Thopter/token swarms backed by anthem effects and artifact synergies attacking out.
- ▸A discounted, oversized improvise spell (Banefire, Comet Storm) as a finisher.
Archetypes
- Artifacts (Affinity/Improvise) — Its improvise grant and artifact recursion make a wide artifact board your primary resource and payoff.
- Spellslinger — Improvise plus UR lets you cast huge X-spells and burn cheaply each turn for value or kills.
- Combo — Cheap artifacts and tutors enable mana-positive loops (Urza, Sai, untap rocks) to generate infinite mana or damage.
- Control — Improvise discounts counterspells and removal while artifacts ramp you into bigger answers and card draw.
