Shaggy Rogers

At the beginning of your upkeep, you may pay 4
life. If you don't, exile Shaggy Rogers.
If a spell or ability controlled by another
permanent or player would cause Shaggy to leave
the battlefield, instead return it to its owner's
hand.
Whenever Shaggy blocks or becomes blocked,
exile X target permanents, where X is Shaggy's
power.
This is but 1% of his power.
