Mirrorhall Mimic // Ghastly Mimicry

If the chosen creature is copying something else (for example, if the chosen creature is another Mirrorhall Mimic), then Mirrorhall Mimic enters the battlefield as whatever the chosen creature copied.

Mirrorhall Mimic copies exactly what was printed on the original creature (unless that creature is copying something else or is a token; see below), except that it's also a Spirit. It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or any Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on. Most notably, if it copies a creature that's not normally a creature, it won't be a creature.

If the copied creature has {X} in its mana cost, X is considered to be 0.
