Merfolk Observer card art
Merfolk Observer enters the battlefield and immediately replaces itself — a 1/1 for one blue mana that draws a card on entry is the baseline of playable in any format that cares about tempo. The body is irrelevant; the cantrip is the whole point.

In Commander, Merfolk Observer slots cleanly into Merfolk tribal builds that want to hit every drop on the curve while keeping cards flowing — Merfolk payoffs like lord effects and Islandwalk synergies make even a 1/1 body meaningful. In Pauper, it competes in blue tempo and Merfolk aggro shells where one-mana cantrip creatures are legitimate role-players, though it sits below the power threshold of format staples. Legacy and Vintage have better cantrip options at every point on the curve, so Merfolk Observer is a fringe consideration there at best. Pauper is where it sees the most competitive daylight outside of casual Commander.
