Honor

Growing your own creature is almost never worth a full card by itself, which is exactly the constraint this design is built around. Bundle that near-worthless growth with a draw, price it at a single white mana, and you get a spell that keeps your hand size steady while leaving a body slightly larger: the counter is the pretext, the replacement draw is the reason to run it. White has historically paid a premium for card draw, gating it behind conditions or stapling it to a body; here the cantrip is nearly free, because the permanent growth on a creature is what pays for it. That growth is also the string attached. The spell needs a target on the battlefield, so it cannot be cast into an empty board, and if the creature is removed in response the draw goes with it: not a true unconditional cantrip, but a cheap one that asks only that you have a creature worth the counter. The strategic axis it turns on is whether a deck wants the counter for its own sake. In a shell that treats +1/+1 counters as a resource (feeding proliferate, evolve-style triggers, or counter payoffs), the growth stops being incidental and starts doing double duty. Absent that, it is a fair-rate cantrip that happens to make one creature bigger. How much the counter matters is the question the format Takes below sort out.
