Departed Deckhand

Text:

When Departed Deckhand becomes the target of a spell, sacrifice it.
Departed Deckhand can't be blocked except by Spirits.
: Another target creature you control can't be blocked this turn except by Spirits.

Rulings:

• 7/13/2018 You’ll sacrifice Departed Deckhand even if you counter the spell that targets it.
• 7/13/2018 If the spell that targets Departed Deckhand has no other targets, it won’t resolve (because it no longer has a legal target after Departed Deckhand is sacrificed).
• 7/13/2018 Activating Departed Deckhand’s last ability after a creature has become blocked by a non-Spirit creature won’t cause that creature to become unblocked.
