The main reason i picked these episodes from your list is because they have some very well written background stories which shed light on the origin of main characters and their past.For instance in Jade Dragon we get to see Jaga young and in Shadow master we have Claudus appearance in the Shadow realm!! Of course ep. like Ghost Warrior, Excalibur are unique of their own!! Also i’d definitely add [FONT=arial][FONT=arial][SIZE=2]Sword in the Hole Key of Thundera
nice to see that you like some of whats on my list. in my list i put some faves that i thought were underrated eps as well which i thought were really good considering the storyline
