Loren, Curious Hunter

Whenever a creature enters the battlefield under
your control, Loren gets a +1/+1 counter.
Then if he has 5 counters on him roll a die.
Odd remove a counter. Even search your library
for a cryptid of mana value less than or equal to
Lorens power. Put that card to the battlefield.
The cryptozoology of today is the zoology of tomorrow
