Juniper Order Rootweaver

A single green pip is the whole design lever. Pay and you get a plain 2/2 with no upside; find a green source and spend the kicker, and the same body walks in growing a creature you control by a counter. The mono-white base cost keeps the card castable in a deck that never touches green, while the optional splash rewards the player who set up the second color with a small stat bump earned at cast. Because the trigger reads "target creature you control," the Rootweaver can pump itself into a 3/3 or hand the counter to a bigger threat already on the board, so it flexes between padding its own body and reinforcing whatever the battlefield already wants sized up. This is a counters-matters enabler folded into an early drop, structured so the green half is upside rather than a tax: the card is never dead if the second color does not show, and never wasted if it does. That thrift is the entire idea. Nothing about it bends a format; the interest lives in how narrow the gap is between a filler two-drop and a modest value creature, and how the whole difference is one mana of a second color paid at the moment of casting.
