Grimgor's Spike: "If attached unit is defending alone, destroy all attacking units when they take combat damage this phase."
How do other people interpret this? I can't figure out if all attacking units are destroyed as long as some units take damage (sort of the inverse of the "dealt damage" rule in the FAQ), or if only the units that were specifically damaged are destroyed.
I would assume the second interpretation, but I'm bothered because the word "all" seems superfluous with that interpretation.
