The Mountains' Protector

When The Mountains' Protector enters the battlefield, all mountains are indestructible,
and it has "{t}: Add {r} to your manna pool".
Legend states that a man with long hair and disproportionately muscled arms compared to the rest
of his body, rides on the back of his giant husky
through the Catalan Pyrenees.
Those who dare to degrade the mountain, must fear.
