Inviolata Securitatem

Flying, vigilance, hexproof
{5}{g}{w}{u}: Emblem. (Put this card from the battlefield into your command zone. It becomes
an emblem. If you cast your commander, while
it is an emblem, it is no longer an emblem.)
As long as Inviolata Securitatem is an emblem, permanents you control have hexproof.
