This is a fairly straightforward card, some sort
of odd hybrid between Aether Adept and Meddling
Mage. I assume it was designed to counteract the
"bad feeling" type of scenario where you bounce
a creature with a comes-into-play ability and
they just replay it and get the ability again -
but Aether Adept style cards, with any
modification, are not the best answer to
creatures with comes-into-play abilities in the
first place. It's not a clear upgrade over its
ancestor in that sense, but it does have
slightly different interactions in cases where
your opponent holds multiple cheap creatures
with the same name, and in situations where you
can reuse it (Deputy of Acquittals, Cloudshift,
&c) and strand multiple different creatures in
your opponent's hand for a turn or two.
