Blue Tutors
Every blue card in Magic that searches your library for the one you need, sorted by how many tracked decks actually run it
What are the best blue tutors in MTG?
The best blue tutors in MTG are the ones players actually reach for, and a handful of those measurably raise your win rate. The list below ranks every mono-blue tutor in Magic: The Gathering by how many tracked Commander decks run it, counted from real games on Playgroup.gg. Where a card has been played enough for us to measure its effect on winning, and that effect is clearly positive, its win-rate lift is shown beside the count.
Deck counts are drawn from 146,944 tracked decks on Playgroup.gg.

The most-played mono-blue tutors
Ranked by the number of tracked decks running the card, not by a rating. A win-rate lift appears beside the few cards whose measured effect on winning is clearly positive.

Tutors in the other colors
A blue deck can also run every colorless tutor, and most Commander decks are not mono-colored:
How this list is built
The candidate pool is every Commander-legal card carrying Scryfall's tutor oracle tag with a mono-blue color identity, minus the cards whose only search is for lands. Multicolor cards are excluded on purpose: a blue tutor should go in any blue deck. Each card is counted across every non-archived tracked deck whose mainboard contains it, and the list is ordered by that count.
Most tutors do not measurably change whether you win. We compare decks that run a card against decks on the same commander that do not, pool those matched comparisons, and ask whether the difference is bigger than chance; only a handful of cards clear that bar. Ordering a list by a number whose confidence interval crosses zero for most of its rows would be ranking sampling error, so the list is ordered by deck count instead and the measurement rides alongside.
A win-rate lift appears beside a card only when it has been played enough to judge and its measured effect is clearly positive: minimums on games with the card, on separate commander groups and on distinct pilots, a cap on how much of the sample any one pilot may hold, and an interval landing entirely above zero. A card that was measured and came out flat gets an empty cell rather than a number near zero, because a number near zero reads as a verdict and this one is not.
Read that figure as a difference, not a multiplier. A +2.2% lift means a deck running the card wins 2.2 percentage points more often than decks on the same commander without it: 27.2% of its games rather than 25.0%. It is not a 2.2% relative increase, and it is not a claim that the card wins 2.2% of your games on its own.
Counts are drawn from 146,944 tracked decks on Playgroup.gg.
