Dragoon of LvB

Whenever Dragoon of LvB attacks, it deals
damage equal to its power to any target.
Whenever a spell or ability would cause a
creature you control to deal damage but the
creature doesn't deal damage as a result of having
0 or less power, draw a card.
Whenever you cast a spell with mana value 0,
copy that spell, except the copy has mana value 1.
