Wrtlf, King of Horrors

When Wrtlf, King of Horrors enters the
battlefield or attacks create a 1/1 black water rat creature token.
Rats you control get +2/+2, have islandwalk and
fear and are horrors in addition to their other creature types.
"Wrtlf's horrors are a force to be reckoned with, but
without him, they are nothing" - The adventurer's
guide to the Rat Lagoon
