Shelter from the 27th of March

You may place a creature that you are playing in this artifact. In this artifact, a creature is considered on the field but can never block or attack and is never a valid target for anything that would destroy the creature. Flip a coin when you end a turn with a creature in this Abnormality. On heads, nothing happens. On tails, another player of your choice may select a creature of yours to destroy.

It literally makes itself into "the safest place on Earth."
