Clever Impersonator

Remember that if you control more than one legendary permanent with the same name, you'll choose one to remain on the battlefield and put the rest into their owner's graveyard.

Any enters-the-battlefield abilities of the chosen permanent will trigger when Clever Impersonator enters the battlefield. Any "as [this permanent] enters the battlefield" or "[this permanent] enters the battlefield with" abilities of the chosen permanent will also work.

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

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

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.

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.
