I was playing the first dungeon with Goblins - (where your chasing the wagon with the baby, er treasure) I believe the card is called "Deflect Missile" Deflect Missile will deflect everything that was Non-melee. Specifically it was deflecting Wavering Faith- which is just a discard card- not an attack card.
Yes, Blocks in general may stop ANYTHING within their domain. It doesn't even have to be an Attack. This includes, say, a Minor Heal you deliberately cast on those Goblins to flush out their Blocks. A fun strategy.
