For some reason I got two
Essence of the Wild tokens and the rest remained Soldier tokens.
Rerolled to start of turn and tried again and got one Essence and four Soldiers.
Rerolled again, three Essence and two Soldiers.
Again and four Essence, one Soldier.
After a few tries, it did create 5 Essence, I did not see any occurrence where they all remained Soldier but have not conclusively ruled that out.
Edit, on the turn after that I played another (real)
Essence of the Wild, which of course became of copy of the 6 other Essences, but for some reason it also became 1/1. It remained 1/1 after the turn ended. My guess it has something to do with the fact the Soldiers were 1/1. But copy-effects are copiable so in the end it should have become a copy of a copy of the other 6/6 Essence.
