That's true, especially as they'll show up a few turns later, so my castle will likely be thinned out by then. Hopefully the war machines have done their job before the enemy can take them out. Chaos Dwarfs are a pretty elite army... unless you take purely Hobgoblins as your core. Even the High Elves might pose a problem with their 50 point Great Eagle drops. Ogres have their 21 point Sabretusks. Which armies don't have cheaper chaff drops than we do? I like that! What's best about it is that it is difficult for your opponent to avoid. The Destroyer is simply too powerful to be ignored.
