Neeko, The Curious Chameleon

You may have Neeko, The Curious Chameleon
enter the battlefield as a copy of another creature
you control, except it has Neeko, The Curious
Chameleon's other abilities.
{1}{g/u}{g/u}: Exile Neeko, The Curious Chameleon,
return that card to the battlefield under its
owner's control at the beginning of the next end
step.
The "legend rule" doesn't apply to permanents
you control.
