Library Parasite

Shuffle Library Parasite face up into an opponent's library as you cast it.
As long as this card is in a library that's not his
owner's, his owner draws an additional card in
their draw step.
If face up Library Parasite would leave a Library it instead comes into play under it's owner's control.
If a player would search their library with a face up Library Parasite in it he may instead put that card
into play under it's owner's control.
