Forum:Can't be special summon except by fusion summon?

I had read that on Dark Paladin's Rulings that even if the card was fusion summoned properly that it still can't be special summoned from the graveyard with a card such as monster reborn. This statement also appears on most of the elemental hero fusions, so does that mean even when they are fusion summoned properly, i can't bring them back to the field with a monster reborn?
