The Great Martyr

Unveil {x}{3} — Unveil this identity only if another identity card has been unveiled or if another player attacked a King player this game.

When The Great Martyr is unveiled, you gain X life and draw X cards. Until end of turn, if a source
an opponent controls would deal damage to a King player, that damage is dealt to you instead. The same is true for losing life, discarding cards and sacrificing permanents.
