The most useful monster is the Dragon King, and that's it. Neither a Djinn nor a Black Dragon can compare to it in terms of power. It's simply a fact. Well, maybe the "Creators" have created someone stronger than the Dragon King. At least, I haven't seen it. If you know, please tell me, I would be very grateful.
Maybe you could vote then? Name the 3 most useful monsters, in your opinion, starting with the best. Then the Dragon King might appear in the ranking.
