Idris, Soul of the TARDIS turns a bargain rare into a combo engine

Idris, Soul of the TARDIS turns a bargain rare into a combo engine

Idris, Soul of the TARDIS looks like bulk until you read the textbox carefully, then it starts looking like a real Commander project. For a card sitting as low as $0.15 on TCGplayer, it brings a rare mix of combo potential, combat pressure, and value looping that budget artifact decks are built to exploit.

Why Idris matters in Commander

Commander is the natural home for a legend like this because the format is built around one commander and a 99-card deck, usually in multiplayer pods. That structure rewards oddball build-arounds far more than 60-card formats do, especially when a commander can turn one artifact into an engine. Idris fits that mold perfectly: it is a {1}{U}{R} legendary creature, Human Incarnation, with Vanishing 3, which already tells you it is meant to be used, reset, and abused rather than simply cast once and left alone.

That matters for deckbuilding because Idris is not a card that wins on raw stats. It is a card that asks for support, then pays you back with scale. In a format full of splashy legends, that makes it easy to overlook, which is exactly why it is interesting now.

How Idris actually works

Idris’s Imprint ability is the heart of the card. When it enters, you exile another artifact you control until Idris leaves the battlefield. Idris then gains all activated and triggered abilities of the exiled card and gets +X/+X, where X is that card’s mana value. If the exiled card has X in its mana cost, that X counts as 0 for mana value, which matters for how you evaluate the best targets.

That text does two important things at once. First, it gives Idris an ability package from the artifact you imprint, so the commander becomes as flexible as your artifact suite. Second, it turns the card into a threat in combat, because the body grows based on the mana value of what you imprinted. A cheap commander that can inherit a powerful artifact ability and suddenly swing as a giant attacker is exactly the sort of hidden engine Commander players keep rediscovering.

The cheapest core combo package

The cleanest line highlighted here starts with Basalt Monolith or Grim Monolith. Imprint one of those on Idris, then pair it with Training Grounds so the untap activation gets discounted. That is the kind of small, efficient support package that turns a fair-looking legend into something far more explosive.

If you want redundancy, Illusionist’s Bracers fills a similar role and gives the deck another way to push the same kind of result. That matters for budget construction, because you do not need a pile of expensive reserve-list staples to make Idris function. You need the right monolith, the right cost-reduction piece, and a commander that can keep the loop relevant.

The practical lesson is simple: Idris rewards you for building around activated abilities, especially ones that become absurd when they are cheaper to reuse. Once that package is online, the card is no longer a curiosity. It becomes a mana engine that can feed the rest of your deck and enable the token, looting, and value loops that the best builds want.

A tight core package looks like this:

• Basalt Monolith or Grim Monolith as the imprinted artifact
• Training Grounds to discount the untap activation
• Illusionist’s Bracers as a backup route into the same plan
• Blink and reset effects to reuse Imprint and keep the engine moving

What the rest of the deck should be doing

Idris gets much better when the deck is built to repeatedly reset or exploit the artifact it has imprinted. That is where blink effects and other enter-the-battlefield synergies come in, because they let you keep extracting value from the same commander instead of treating it as a one-shot effect. In practice, that means the deck can drift toward repeatable artifact abuse rather than a simple goodstuff shell.

The coverage around Idris also points to a broader payoff pattern: once the engine is running, the deck can draw cards, make tokens, and chain into looting and other value loops. That is the real reason the card is worth attention. It is not just about infinite-mana-style turns, it is about turning that mana into a board state and a hand that keeps refilling.

That also makes the deck more accessible than it first appears. You do not need to chase the most expensive artifact finishers to make Idris feel powerful. You need a tight package of artifact abilities, ways to reuse them, and enough payoff density that every reset matters.

Idris can also win fair games the hard way

The combo line is the headline, but Idris is not locked into combo-only play. Imprinting a huge artifact can make the commander a serious attacker, and the examples that stand out here are Metalwork Colossus and Mycosynth Golem. Both can turn Idris into a much larger threat, which matters when a commander can already grow based on the mana value of the exiled artifact.

Excalibur, Sword of Eden pushes that plan even farther by giving Idris a route to lethal commander damage. That makes the card feel less like a narrow puzzle piece and more like a flexible build-around that can pressure life totals while still threatening a combo finish. In Commander, that overlap is valuable because it keeps opponents guessing and makes your opening hands matter more often.

Why this bargain rare deserves a build

The Doctor Who Commander decks released on October 13, 2023, and they are still giving up hidden tech long after the initial release window. The product line included Blast from the Past, Timey-Wimey, Paradox Power, and Masters of Evil, and Idris is a good reminder that the most interesting cards from a crossover release are not always the obvious headline legends.

That is the real draw here: Idris is underpriced because it asks for construction, not because it lacks ceiling. In a format built around one legendary creature and a pile of synergistic support, that is often where the best budget discoveries live. If you want a commander that turns monoliths, blink effects, and artifact oddities into a real engine, Idris is not a joke card at all. It is a bargain rare with the kind of ceiling that only looks hidden until someone finally assembles the right shell.
