Whenever a Hippo enters your graveyard create
a 3/3 green Hippo with trample.
Whenever a Hippo leaves your graveyard, if it
enters the battlefield you may pay {3} and 3 life
and make a copy of it, except it is not legendary.
If it does not enter the battlefield shuffle it into
your library instead.
