Pinkie Pie

Whenever Pinkie Pie enters the battlefield,
search your library for a creature card and
put it into your hand. Each opponent may
search their library for a creature card and
put it into their hand. For each opponent
who searches a library this way, search your
library for a creature card and put it into your
hand. Then each player who searched a library
this way shuffles it. If no opponent searches
their library this way, transform Pinkie Pie.
