Harvesttide Sentry

A 3/1 for two mana that wants to swing on turn three regardless, this is the version of coven that keeps the ask cheap. The trigger checks for three creatures of different powers at the start of combat, which is a genuine deckbuilding constraint (a board of identical tokens fails it), but the reward is narrow enough to price the whole package aggressively: an evasion window against blockers of power two or less, printed on a body that dies to almost anything. The 3/1 wants to attack anyway, so the coven check reads less as a value engine than as a nudge toward the slightly diversified curve you were probably building. It renders the coven contract honestly: the payoff is conditional and modest, the condition is easy to hit once your creatures naturally spread across power values, and the failure state (a blank line of text) costs you nothing on a green two-drop you would play regardless. It sits at the floor of the coven spectrum, the common that shows what the mechanic looks like before the rares start bolting card advantage and removal onto the same trigger. Coven asks you to trade board efficiency for a payoff more often than not; here the trade is small and the payoff smaller, which is exactly what makes it a clean read on the mechanic's baseline.
