Question about Kuraz and rate/fix my monarch deck?!?

All Monarchs can be Special Summoned by means such as Call of the Haunted, but only Kuraz gets his effect that way. To Normal Summon ANY lvl 5 or 6 monster, you need to tribute a monster. Kuraz doesn't have any sort of Special Summoning condition that states "This card can be Special Summoned by...", just that he gets his effect WHEN he is Special Summoned by another card effect.
