Thought Vessel
Thought Vessel appears in 18% of tracked Commander decks on Playgroup Live. When drawn, 75% of copies reach the battlefield, with a median first-cast turn of 5.0.
Thought Vessel earns its slot in 18% of Commander decks tracked on Playgroup Live. That figure covers 989 of the 5494 distinct decks that have played a tracked game, with 638 unique players contributing data and no single player accounting for more than 28% of the sample. The dataset is well-spread.
The card does two jobs for 2 mana: it taps for colorless mana like a Manalith, and it permanently removes your maximum hand size. That second ability is the differentiator. Commanders that draw deeply, discard-matters strategies, and high-card-count value engines all want the no-hand-size clause. The broad spread across commanders in the tracked data reflects exactly that range of use cases.
75% of drawn Thought Vessels are cast before the game ends. A median cast turn of 5.0 puts it squarely in the mid-game ramp window, though the distribution runs from turn 1 through turn 19, reflecting how differently players sequence their mana rocks depending on what else they draw.

First-cast turn
n=338The "good card" funnel
1621 brought · 638 playersOf 1621 Thought Vessels brought to games, 450 were drawn, 338 of those were cast, and the majority stayed on the battlefield through end of game.
Players who cast this card win 29% of the time (n=337) , vs 25% when it never left the library (n=1069).
When players drew this card but left it in hand, they won 31% (n=110) — about the same as leaving it in the library. Those players survived long enough to draw it, so the gap above is about the card resolving, not just about surviving.
Observed gap +4.2pp; 95% confidence interval -0.8pp to +9.2pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
497 instancesMost Thought Vessels that are brought to a game never leave the library, a structural reality of 100-card singleton rather than a statement about the card's power. Of the copies that were observed, the large majority finished on the battlefield.
