Doom Prevails Precon Upgrade Guide: Stay in Bracket 2

The short Doom Prevails precon upgrade guide: upgrade it if you like the idea of winning by throwing lands away. msc-6msc-6Shop on TCGplayer Doctor Doom, King of Latveria makes each opponent lose 2 life whenever you discard land cards, and every turn he hands one of your Villains menace and makes it connive. The box already has the plan. What it lacks is enough ways to connive and enough reasons to be happy about a discard, and five cards fix most of that.

Doom Prevails is one of the four Marvel Super Heroes Commander decks Wizards released on June 26, 2026, the blue-black-red Villains deck next to the Selesnya Wakanda Forever precon and the four-color Fantastic Four precon. Doctor Doom is its face commander. msc-407msc-407Shop on TCGplayer Loki, the Deceiver isn't a partner; he's a second legendary Villain in the 99 that can lead the deck if you'd rather attack.

What's in the Doom Prevails box

That's the deck's whole problem in one table. Twenty cards mention discarding, but only nine make you connive, and Doctor Doom is one of them. On many turns his combat trigger is your only connive, so his drain fires when you happen to draw a land at the right moment.

How the deck wins

Connive means draw a card, then discard a card, and if the discard wasn't a land the creature gets a +1/+1 counter. It first appeared on New Capenna Commander cards in 2022. Doom turns the land half of that choice into reach: a land you'd never play becomes 2 life from each opponent instead of a dead draw. The nonland half grows your Villains, and the menace Doom hands out makes those bigger Villains hard to block.

Loki, the Deceiver pushes the combat side. When he attacks he makes a tapped, attacking copy of another Villain you control, and whenever your Villains deal combat damage to a player you draw a card. You don't have to win in combat, but combat damage and drain add up against the same life totals. Keep an eye on all three opponents, because a drain trigger can put someone in range of an attack you'd otherwise ignore.

Five upgrades, priced

We picked cards that make you connive or discard more often, or pay you when you do. Prices are the cheapest paper printing on Scryfall on October 19, 2026.

Norman Osborn is the upgrade we'd buy first. A two-mana creature that can't be blocked and connives every time he connects adds a connive trigger on almost every turn he attacks, and he's a creature you can point Doom's combat trigger at too. Later you can pay {1}{U}{B}{R} at sorcery speed to flip him into Green Goblin, a flier with menace that makes spells you cast from your graveyard cost {2} less and gives every nonland card in your graveyard mayhem. Mayhem only works on a card you discarded that turn, so Goblin rewards conniving and casting in the same turn, not digging through the whole yard.

Bone Miser is the payoff the stock list is missing. Every discard the deck makes now produces something: a body, two black mana, or a card. Discard a land to Doom's connive and you get the drain and the mana in one go.

Crucible of Worlds fixes the cost side of the plan. Lands you discard to Doom come back as land drops, so you can throw away lands early without stumbling on mana later. It costs about as much as Bone Miser, so if money's tight it's the one that can wait.

An Offer You Can't Refuse is one blue mana for a counterspell, which leaves you mana to develop on the same turn. The two Treasures it gives away matter less in a four-player game than in a duel.

Oscorp Industries is a dual land for this deck that's also a discard you don't mind. Discard it to a connive and you can still play it from your graveyard that turn, losing 2 life when it enters. Doom's drain triggers on the discard either way.

Together the five come to a little under seventy-five dollars at those prices, and none is a Game Changer.

What to cut first

Tri-Sentinel, Act of Vengeance (msc-115msc-115Shop on TCGplayer) costs seven mana. It's a flier with menace and trample whose enter trigger deals 3 damage to up to one creature for each opponent, and it can come back with unearth for another seven. That's a lot of mana in a deck that wants to spend its turns conniving, and it's the first card we'd take out.

Superior Foes of Spider-Man (msc-167msc-167Shop on TCGplayer) only does something when you cast a spell with mana value 4 or greater. This deck wants to cast cheap spells and connive, so it rarely triggers.

Vandalblast destroys artifacts you don't control. It's a fine card when an opponent leans on artifacts, but it does nothing for the discard plan, so it's an easy slot to free up unless your group is full of artifact decks.

For a third and fourth cut, look for cards that don't connive, don't discard and don't punish anyone's life total. Our color identity guide is worth a look before you add anything with hybrid or Phyrexian mana symbols.

Bracket check

The stock 100 has no Game Changers, and none of the five additions is on the list, so the upgraded deck has nothing that forces it above Bracket 2. That isn't the same as being a Bracket 2 deck. In October 2025 Wizards stopped defining Bracket 2 as "the average precon," so where the deck lands depends on how quickly and reliably it wins. Add even one Game Changer and it's Bracket 3 at least. Our Commander Brackets guide has the full rules, and the honest move is to tell your table what the deck does before the game starts.

What upgraders are saying

When the decklist went up in June, an r/EDH thread complained that Doom doesn't prevail in his own precon. The top reply made the case for him: "Dooms land text is about connive too; you only get the +1/+1 counter from connive if you discard a non land, so Doom fixes the "downside" of discarding lands with some damage." (comment). In an October thread asking whether the deck is worth upgrading, one player went further with our first pick: "I'd swap him for Green Goblin and use the connive triggers for cheap casts." (comment).

The Command Zone's $50 upgrade video for this deck makes ten additions and ten cuts. It's a good second opinion if you want more swaps than the five above.

Our take

We'd upgrade Doom Prevails, and we'd do it in this order: Norman Osborn and Oscorp Industries first because they're cheap and change how often you connive, then Bone Miser, then Crucible when you can afford it. Take out Tri-Sentinel before anything else. Skip the urge to add generic Grixis staples; a card that doesn't connive, discard or drain makes this deck worse at the one thing it does well.

How we checked this: we pulled the full 100-card list (Wizards' decklist article and MTGJSON) and counted it against Scryfall's rules text on October 14, 2026, then re-priced every addition at its cheapest paper printing on Scryfall and re-checked the Game Changer flag on all 100 cards and the five additions on October 19. The data is kept with our sources.
