Deepmaw Kraken

Defender
Whenever Deepmaw Kraken submerges, the
owner of up to one target Vehicle puts it on the
top or bottom of their library.
{t}: Submerge—Deepmaw Kraken loses defender
until end of turn. (This creature phases out. When
it phases in, it loses defender until end of turn.
Submerge only as a sorcery.)
