Wary Watchdog

The 3/1 body is the tell: this is a green two-drop built to be spent, not protected. One toughness means it dies to almost anything, and the design leans into that fragility rather than fighting it. Surveil triggers on both ends of its life cycle, so trading it in combat or feeding it to a sacrifice effect isn't a loss of value but a second helping of the payout. Most graveyard-oriented enters-the-battlefield creatures ask you to arrange a separate way to kill them; this one folds the death trigger into a stat line that all but guarantees it happens. Green rarely gets this flavor of card-selection smoothing, and pairing it with recursion lets you re-trigger either surveil while blink re-triggers the enters surveil. As aggressive filler it's a cheap 3-power threat that thins toward your next play; as an engine piece it's a small, repeatable dig that wants to die. The one point of toughness makes it a poor blocker and a poor long-term board presence, which is precisely the calibration: the reward is priced for a creature you expect to cash in fast rather than one you hope survives to the next turn.
