Voracious Manticore

{4}{r}{g}: Monstrosity 3. (If this creature isn't monstrous, put three +1/+1 counters on it and it
becomes monstrous.)
"I once herd of a tale that a manticore once massacred
an entire city state, not out of hunger, but rather for the
joy of killing. It took six Akros soldiers to bring down
the beast. Of those six, only one survived. Since then,
that tale has been a reminder of the growing dangers
that threaten the city states."-- Brigone,
soldier of Melts
