Hex sealed fusion question?

Question

Hey I need some help on the rulings because different people say different so if I use the first effect of the dark hex sealed fusion to subsistute does it have to be dark or can it be fire?

Because the second effect says if I use the second effect it has to be dark. I was just wondering because their are two different effects and I heard you can you its second effect without polymerization (thats why it has to be dark). I was just wondering I need help with rulings Thanx everyone.

Answer 1

for all the hex sealed fusions, the first effect simply means that they can be used as substitutes for fusions (polymerization, miracle fusion, etc.).

the second effect (tributing to summon a fusion monster) is just tributing the hex sealed fusion and another monster to summon a monster with the same attribute as the hex sealed (so you can use the dark hex and dark magician/ buster blader to summon dark paladin). the second effect does not properly fusion summon so you can't bring back the fusion monster if it was destroyed

Answer 2

it can subsitute any mitirel but a hex-fusion monster can somen a fusion of the same attribute if it's on the field without polymerazation (but ya still hafe to ues the mitirels)

so to put it simpel;

they're like "super-powered polymerazation"
