Gigantoplasm

If the chosen creature is copying something else (for example, if the chosen creature is another Gigantoplasm), then Gigantoplasm enters the battlefield as whatever the chosen creature was copying (plus any abilities it gained as part of the copy process, if applicable).

The activated ability Gigantoplasm gives itself becomes part of its copiable values. Unless the ability is overwritten by another copy effect, a creature that's a copy of Gigantoplasm will have that ability.

If Gigantoplasm somehow enters the battlefield at the same time as another creature, it can't become a copy of that creature. You may choose only a creature that's already on the battlefield.

You can choose not to copy anything. In that case, Gigantoplasm enters the battlefield as a 0/0 Shapeshifter creature, and is probably put into the graveyard immediately.
