IJN Amagi

Lifelink
If IJN Amagi would die, exile it instead. Return it
to battlefield as an enchantment - aura with "Enchant creature you control" and "Enchanted creature gets +3/+3, lifelink, and 'Whenever this creature attacks, you may draw a card.'"

{1}{b}{g}, Sacrifice IJN Amagi: Each opponent sacrifices a creature. You gain life equal to the sum
of the powers of the sacrificed creatures.
