Bob Blessed by Dirt

Bob's power is equal to your devotion to {c}. (The total
amount of {c} in the mana cost of permanents you
control counts toward your devotion to {c})
Whenever you cast a colorless spell draw a half card.
(To draw a half card cut the top card of your library in
half and add one of those halves to your hand. When
you cast that card also cast another half of any half card
in your hand.)
Apparently, he is 'blessed by dirt'
