Casey of the Jank

When Casey enters the battlefield, you may
search your library for up to two forest and/or
island cards and put one on to the battlefield and
the rest into your hand, then shuffle.
{1}{g/u}: Target land you control becomes a 4/4
blue and green Ooze creature until Casey of the
Jank leaves play. It's still a land.
And nothing makes sense anymore!
