Castaway Bomb

When Castaway Bomb is cast onto the battlefield,
discard it immediately and create a Castaway Bomb
Token and shuffle it into an opponents deck. (It's
an artifact with "If you draw this card, you must
reveal it and lose 5 life and discard one nonland permanent that you control. Then, exile this token.")

New security measures were placed after a self-destructing bomb and two hellkite dragon eggs blew
up on a battleship near the edges of Imuru.
