Clever Impersonator

If the chosen permanent is a copy of something else (for example, if the chosen permanent is another Clever Impersonator), then your Clever Impersonator enters the battlefield as whatever the chosen permanent copied.

If Clever Impersonator enters the battlefield as a copy of a planeswalker, it will enter the battlefield with a number of loyalty counters on it equal to the loyalty printed in the lower right corner of the planeswalker card. It won't copy the number of loyalty counters on the original planeswalker.

If the chosen permanent is a token, Clever Impersonator copies the original characteristics of that token as defined by the effect that put that token onto the battlefield. Clever Impersonator is not a token.

Clever Impersonator copies exactly what is printed on the chosen permanent (unless that permanent is copying something else or is a token; see below). It doesn't copy whether that permanent is tapped or untapped, whether that permanent has any counters on it or any Auras and/or Equipment attached to it, and it doesn't copy any non-copy effects that have changed that permanent's power, toughness, types, color, abilities, or so on.

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

You choose which nonland permanent Clever Impersonator will copy, if any, as it enters the battlefield. This doesn't target that nonland permanent.
