Consort Radahn

Double strike, Vigilance
You may cast Consort Radahn from the command
zone by paying {5}{w}{u}{b}{r}{g} and X life, where X
is twice the number of times he's been cast from the command zone this game.
Whenever Consort Radahn is dealt excess damage,
you may prevent that damage. If you do, each
player loses life equal to the damage prevented this
way. Exile Consort Radhan, then return him to the battlefield transforemed.
