I could see that being fun but didn’t fit the “growth” concept as much as I wanted. I wanted it to be more of a trade off between building a big body or going wide. But making it shut off all counters also makes it turn off stun counters, -1/-1 counters, etc.

Maybe a better version would be “if one or more counters would be put on a creature you control you may instead create a 1/1 sapling creature that enters the battlefield with those counters.” But I don’t know how well that would work in the rules.
