Immortality Field

Defender
Immortality Field can't have indestructible or hexproof. You can't lose the game.
When Immortality Field enters the battlefield,
target a creature. If that creature is tapped, it and
other tapped creatures gain indestructible and hexproof. If that creature is untapped, it and
other untapped creatures gain indestructible and hexproof.
Sacrifice this token at the beginning of your
end step.
