Doctor Doom, King of Latveria costs {1}{U}{B}{R}. Whenever you discard one or more land cards, each opponent loses 2 life. At the beginning of combat on your turn, a Villain you control gains menace and connives: you draw a card, discard a card, and if you discarded a nonland card it gets a +1/+1 counter.

The precon already has the Villain support and the connive creatures, including Ultron, Unlimited, Iron Monger and Baron Strucker. Each swap below pairs a cut with an add, and every card is scored with the same numbers the Oracle uses to build decks: synergy and inclusion from the Doctor Doom decks, plus lift, which shows how much more often a card turns up in these decks than in decks that could play it.

What is holding the deck back

A pile of Villains almost nobody plays

Batroc, Klaw, Titania, Stilt-Man, Helmut Zemo and Damocles Base are each played in about one Doom deck in four or fewer, and Batroc is not played in the commander's decks at all. They are Villains, but they do nothing with discard or connive.

Missing discard and connive engines

Leader, Super-Genius, Magmakin Artillerist, Archfiend of Ifnir and M.O.D.O.K. each turn discarding or conniving into damage, counters or cards, and the precon leaves them all out.

A heavy top end

Nine nonland cards cost six or more, including Tri-Sentinel at seven mana, Abomination at eight and Extract Power at six. Cheaper cards keep the connive engine running every turn.

Batroc is a two-mana Villain with multikicker {2}, and it is not a card Doom decks usually play.

Leader, Super-Genius costs {2}{U}{U}. If a creature you control would connive, you draw a card first, then it connives, and at the beginning of combat on your turn a creature you control connives. With Doom's own combat trigger, that is two connives and an extra card each turn. It is the highest-scoring card the precon leaves out.

What to keep

These cards are doing the deck's heavy lifting. Do not cut them.

If you want to spend more

These are strong but sit outside a budget upgrade. Prices are the cheapest paper printing.

The verdict

Doom Prevails already plays the Villain core and the cost reducers. The upgrade is cheap discard and connive engines that turn every discard into damage, counters or cards, fewer Villains that do nothing for the plan, and fewer six- and seven-drops. These fifteen swaps cost about $41 in total.

How the numbers work

Inclusion is the share of Doctor Doom, King of Latveria decks (11,607 of them when this was written, 2026-10-27) that play the card. Synergy is how much more often they play it than other decks in the same colours. Oracle score is synergy × 0.6 plus inclusion × 0.4, the same blend The Oracle uses to rank cards for a deck. Lift compares how often the card appears in these decks with how often it could, capped at 8× here; it is shown for context and does not change the score.

Two cautions. Players who run the precon unmodified count as Doctor Doom decks, which flatters every card the precon contains. Lift is high for nearly every Marvel card here because they are new and rarely played outside Villain decks, so use lift to compare cards, not to judge one in isolation. A card the commander's decks do not usually play counts as 0 in the average score. Prices are the cheapest non-foil paper printing on TCGplayer (via Scryfall), in USD, and move daily.
