I assume this means dragon and it so it's because its sacred order only. 

Yeah, I'm sure they meant that and not Fire Knight. But to the OP, the fine print in the quest says you have to use all members from the Sacred Order in order to earn points. I often find that some of these quests make me slap my forehead after I spend over 1000 energy and earned nothing. =(

These style tourneys its all about the prisms for me.  I solod 20 with SO food to also do some work on the champ training.  Definitely not every player friendly events though.
