Artifact Creature — Phyrexian Horror

Murders at Karlov Manor Commander (MKC)
When Psychosis Crawler hits the battlefield, its controller wins 55% of the time — a +21 percentage-point lift over the 34% baseline win rate logged when it sits in the library all game.
Psychosis Crawler appears in just 3% of tracked Commander decks, but when it resolves, the numbers tell a compelling story. Across 102 tracked games on Playgroup Live, decks that actually cast it won 55% of the time, compared to 34% when the Crawler never left the library — a raw delta of +21 percentage points.
That gap is directional, not definitive: the cast bucket holds only 20 observations, well below the threshold for statistical confidence. Still, the early signal is consistent with what the card does. A five-mana creature that scales with hand size and drains opponents every time you draw a card is a game-closing engine in the decks that want it. The median first-cast turn is 8, which means players are typically holding it until a critical mass of cards is in hand before deploying it — supported by a same-turn-cast rate of just 37% and a median hand-wait of 1 turn.
The commander distribution confirms the archetype profile: blue-heavy wheels and card-draw commanders dominate the list, led by Krang, the All-Powerful and Ms. Bumbleflower. Psychosis Crawler is a niche role-player, not a format staple, and the 3% inclusion rate reflects exactly that.

The top 10 commanders span blue-heavy wheels, forced-draw, and card-advantage archetypes, showing a tight and coherent synergy profile rather than a spread across the broader meta.
How often is Psychosis Crawler drawn in a Commander game? ▾
In tracked games where Psychosis Crawler was in the deck, it was drawn in 33% of deck-participations. That is notably higher than the typical singleton draw rate, likely reflecting that many of its home decks actively prioritize card draw, increasing the odds of hitting the Crawler along the way. Of the 36 instances drawn, 20 were cast — a draw-to-play rate of 53%.
What turn does Psychosis Crawler usually hit the battlefield? ▾
Median first-cast turn is 8, with the middle 50% of casts landing between turns 6 and 9. Only 2 of 20 casts happened on turn 4 or 5, which aligns with its five-mana cost and the strategic profile: players tend to wait until they have a meaningful hand size before tapping out for the Crawler to maximize its immediate drain impact.
Does casting Psychosis Crawler actually help you win? ▾
The early signal is yes, but the sample is small. Decks that cast it won 11 of 20 games (55%), versus 25 of 74 games (34%) where it sat in the library the whole time. That +21 percentage-point delta is the largest win-lift signal in the dataset for this card, but with only 20 cast observations the number should be treated as directional rather than conclusive.
Why does Psychosis Crawler have low battlefield stickiness? ▾
Only 45% of cast copies remained on the battlefield when the game ended — 9 of 20 instances. That is low relative to artifacts in general, which tend to dodge sorcery-speed removal. The Crawler's high threat ceiling draws immediate answers: a creature that drains every opponent each time you draw is exactly the kind of permanent tables kill on sight. The 16 graveyard finishes out of 109 brought instances confirm it is removed regularly.
Which commanders most commonly pair with Psychosis Crawler? ▾
The list is dominated by blue-based card-draw and wheels commanders. Krang, the All-Powerful leads with 10 decks, followed by Ms. Bumbleflower (9) and Queza, Augur of Agonies (8). Nekusar, the Mindrazer and Yusri, Fortune's Flame also appear, rounding out an archetype profile centered on forcing opponents to draw or drawing aggressively yourself.
Is Psychosis Crawler legal in Commander? ▾
Yes. Psychosis Crawler is legal in Commander, Duel Commander, Legacy, Modern, Vintage, Historic, Timeless, Gladiator, Brawl, and Oathbreaker. It is not legal in Standard, Pioneer, Pauper, or Pauper Commander. Its colorless color identity means it can slot into any Commander deck regardless of the commander's colors, which is a notable flexibility advantage for a card this synergy-dependent.
