Ventos, Darkened sky

When Ventos enters the battlefield, target
creature you control gets +X/+X until end of
turn, where X is the amount of mana spent to
cast Ventos. At the beginning of your upkeep
on each of your turns, target opponent loses 1
life for each creature they control with a power
of three or more. You have no maximum hand
size. Each time an opponent loses life draw X
cards, where X is the total life lost. If an
opponent attacked with a creature with a power
of 4 or greater they lose 4 life.
