Cool thing about A2 assassins is no need to wait until your castle is sieged - you can cloud trapeze them one step ahead of an invading army. If you correctly anticipate where the army is going, you can have 7 or 8 orb lightning spewing assassination attempts while your (glamoured) defensive army moves to intercept the remainder of the army which actually moves.
Heh, think your big army of dual blessed guys are bad? Try them without a priest!
