Come along, dear
I think it's a Trap called Curse of Darkness that does it.
This monster’s second effect cannot be used to Special Summon Fusion Monsters that can only be Summoned by Fusion Summon, such as “Dark Paladin”.
Alright, here's one considering the multiple wordings on Special Summonings. You know how there are too forms of 'exclusive' Special Summoning?
"This monster cannot be Special Summoned except by Fusion Summon...."
"This monster can only be Special Summoned by Fusion Summon...."
I believe there's a difference, if not, stop me now. Now, the ruling of The Light - Hex Sealed Fusion states:
Now, and Elemental Hero Fusion says the former of the two above, "cannot", rather than "can only" like the ruling on Hex. Does that mean that Hex's second effect can be used on Hero Fusions?
just say a monster can only be special summoned by tributing 3 monsters (or other things), could i use a monster reborn, or other revival card to special summon it, but still having to sacrifice the required cards?
