not really
paladins can give another unit an extra turn which is great
royal snake got a distant attack and no retalitation
assasins can only use their ranged attack once and they have to kill a stack before they can reuse it not worth it
royal snakes way cheaper and strong
in large quantiies royal snakes can kill a troll in 1 hit
give them another turn from paladins and another troll goes down
sure they are nice at night and cyclops too
but that is if u understand the game better
like u said yourself he doesn't utilize his units abilities
so why let him use it?
give him sometihng else that CAN work for him
