Nagging Thoughts is a two-mana instant that replaces itself and lets you pitch an unwanted card — clean card selection at a negligible cost. The madness clause is where it stops being filler and starts being a role-player.

Nagging Thoughts is a bulk common in most formats, but Pauper is where it earns genuine consideration — madness synergies are real there, and the instant speed matters in a format full of interaction. In Commander, it's fringe: the selection is real but one card at sorcery-equivalent value doesn't move the needle at 100-card scale unless your commander rewards discard or madness specifically. Legacy and Vintage have far stronger cantrips, so Nagging Thoughts doesn't see play there outside niche madness builds.
