Glastonbury

{4}{r}{g}{w}: Monstrosity 10 (If this creature
isn't monstrous, put ten +1/+1 counters on
it and it becomes monstrous.) As long as
Glastonbury is monstrous, it has trample.
While this is Monstrous, all Artifacts and
Equipped Creatures gain Persist.
If five or more cards have -1/-1 counters,
transform this.
