Terrasymbiosis If you've ever said, "I wish Green had a Beast Whisperer but for +1/+1 counters," then meet your dream enchantment

Most likely the current $20 tag will correct itself to about $15 in the coming months or even lower than that
So, the fact you can cast this as an adventure at some point too is great, especially because an instant speed Divination-like effect is itself probably already playable
Control players in particular might find the idea of casting an instant-speed Faithless Looting abhorrent, as its card disadvantage without graveyard synergies
This is a little bit clunky and you have to be careful about when you cast it -- but when the coast is clear, it's going to kill something and make your creature a better attacker at the same time
