The Veil

When The Veil enters battlefield, search for
a creature or a Seth Planeswalker from your
hand or deck and attach it to The Veil.
The card attached does not count as being played
and may not be the target of spells or abilities.
Shuffle your deck if a card was searched this way.
When The Veil leaves the battlefield, the card
attached comes into play if you own a
Methuselah. Otherwise sacrifice the card.
Any player may sacrifice two Historic
permanents to exile The Veil.
