Essence of the Wild

Because creatures you control enter as copies of Essence of the Wild, any "enters" triggered abilities printed on such creatures won't trigger.

If a creature such as Cryptoplasm that's already on the battlefield copies Essence of the Wild and modifies its own copy effect, that modification is also copied by creatures entering under your control.

External abilities may still affect how a creature enters. For example, if your opponent controls Urabrask the Hidden, which reads, in part, "Creatures your opponents control enter tapped," a creature entering under your control will be a tapped Essence of the Wild.
