Neleth, Collector of Copies

Whenever a permanent you control enters the battlefield as a copy of another nonland
permanent, gain control of all permanents
with the same name.
{2}{u}{u}{t}: Return target nonland permanent you control and all other permanents with the same
name to their owner's hand. Draw a card.
Sometimes a good copy can hold as much beauty as
the original. I'll keep both to be certain.
