The only less clear part I see in Thorn Carapace is the ommission of the "75%" but if you want to suggest a better wording that's in keeping with the rest of my cards then feel free to go ahead and do so.
Emerald Shield is not a hard counter since it lacks "Enchanted" status and is thus targetable with PC.
I never meant to imply "Umber" was the real name, it's simply the colour I have given earth.
Phoenix is considered an "Eternal" being and Fate Egg is considered to be a container of life rather than a living thing in and of itself. As such, they trigger death effects normally but aren't part of the set of "living" creatures that some cards reference.
I don't recall Forest Scorpion having 2HP but that hardly seems overpowered so...
Also, added Fire.
