Conquest

Horsemanship, vigilance
Conquest's power is equal to the total number of creatures on the battlefield.
Conquest's toughness is equal to the total number of creatures in the graveyard plus 1.
"I looked, and behold, a white horse, and he who sat on it had a bow; and a crown was given to him, and he went out to conquer."
- Revelation 6:1-2
