there are 2 weapons in TW that you cant really defend,
real fakes - a fake train that contains a nuke (you get one fake train ot each of your villas, random 10 of them are nukes with cats), you cant defend everything all the time...
fake noble trains - i attack 5 of your villas with noble trains but i send 10 trains (40 nobles) so i force you to spread your troops thiner than usual as you clearly see 10 noble trains but i wasted only 5 worth of troops to take 5 less defended villas and all at the cost of 20 packs..
