trupheus yeah but you can only have so much buildable land per castle, so taking someone with +100 land down to 1-2 castles would cause cascading failure, their troops would abandon, etc... Then hit em with a few attacks/rubbers, completely crippled in a few minutes. Probably best to run the trousers right before the tick, then at the tick when everything has abandoned then go in for a few attacks to finish the job.
