Graf, Lord of the wastes

Flying, Trample
Lands you control lose all abilities and become
lands called Wastes that have {t}, {c}
When Graf, Lord of the wastes attacks, destroy
target land defending player controls and add {c}{c}{c} to your mana pool. You dont lose this
mana as steps and phases end.
Exiled from his former kingdom, Graf now wonders the ancient land of dust and debris, searching for weary traveler that would make an excellent feast.
