Diresight

In Commander, Diresight is a niche role-player rather than a staple — it earns a slot specifically in decks that reward knowing opponents' hands or care about controlling their draw, and outside those shells it underperforms compared to cheaper cantrips or more impactful interaction. In competitive 1v1 formats like Legacy and Vintage, three mana at sorcery speed for a non-permanent effect is simply too slow; Diresight never sees play there. Modern and Pioneer are similarly uninterested — the formats' cantrip and disruption suites are efficient enough that a three-mana look-and-redirect doesn't make the cut. Pauper is the one non-Commander format where Diresight could theoretically see fringe experimentation in control shells hungry for hand information, but even there the mana cost is a hard barrier.
