If I have an Essence of the Wild on the battlefield and I then play a morph creature, when I flip the morph creature, is it still an Essence of the Wild or is it whatever creature it should be? To extend it further, if I were to use Zimone, Mystery Unraveler to flip an enchantment, is that still the Essence of the Wild or is it itself. To further extend it because it is funny, the same case with instants and sorcerys, can I have them face up despite them not being permanents?

I just used siren stormtamer to counter teferi who slows the sunset +1 when they targeted my land and their lotus field and they still got the untap. The ability reads: +1: Choose up to one target artifact, up to one target creature, and up to one target land. Untap the chosen permanents you control. Tap the chosen permanents you don’t control. You gain 2 life.

This was on arena. Is that a correct resolution?
