Lizard Priest

As Lizard Priest enters the battlefield, create a
4/4 white Lizard Skeleton creature token.
{4}{g}{u}: Monstrosity 3. (If this creature isn't
monstrous, put 3 +1/+1 counters on it and it
becomes monstrous.)
When Lizard Priest becomes monstrous, search
your library for up to two Lizardbone Cleaver
cards and place them onto the battlefield.
