Poised Practitioner

The +1/+1 counter here is a receipt for behavior you were already going to reward: casting a second spell in a turn. Flurry attaches growth to the spell-count trigger, so this Monk sizes up as a byproduct of doing what a spellslinger deck does anyway, and the scry that rides along smooths the very draws that let you hit two spells the following turn. That feedback loop is the design intent: the more you chain, the faster the body climbs and the cleaner your top-of-library gets, which in turn makes the next flurry easier to assemble. The restraint is that all of it is passive and contingent. There is no activated ability, no way to trigger the counter twice in a turn, and a turn where you cast only one spell leaves it a plain 2/3 doing nothing but blocking. The card asks the deck to supply the tempo rather than generating any itself, which is the trade white makes for putting a self-fueling threat this low on the curve. Creatures that convert a deck's incidental cast-count into a growing clock are an old idea, but the scry is the wrinkle: most such payoffs reward the volume and stop there, while this one quietly improves the fuel supply every time it fires.
