Elrath, Orzhov Healer

Elrath, Orzhov Healer Is not a creature unless your devotion to White and Black is Seven or greater.
As long as Elrath, Orzhov Healer is on the
battlefield, whenever a creature attacks, you
gain one life.
{w}{b}: Pay X life. Target creature gains +0/+X and lifeline until end of turn where X
is the amount of life you lost this turn.
{w}{w}{b}{b}: All players must attack on their
next turn if able.
Gaze upon my numbers, and weep.
