Masked heros are simply fusion types to incorporate into other decks namely elemental heros, so scratch that as a deck cause they're all fusions. Once again evil heroes arent really a deck they're all fusions safe 3 cards. As far as hero decks are concerned they are elemental heroes and destiny heroes. Elemental heroes are really big right now with the conjunction of the masked heroes, competitive viable for sure. As for destiny heroes they are making a comeback for sure, they should be competitive already or soon enough.
