  Official Ruling
  This ability checks whether you control any Goblins twice each turn: once when the ability would trigger, and once when it resolves. If you control any Goblins at either time, you won’t sacrifice Stenchskipper. (If you control any Goblins at the time the ability would trigger, it doesn’t trigger at all.)
