I have golden Bendictus I wanna use him but I also need dust.Is there any good decks I can use him or should I disenchant him?

Well Benedictus sees more play in wild than standard and he isn't one of those cards that is good in almost any situation so I'd say it is a safe disenchant. However, the card is pretty fun in control and steal priest so there is that.

What do you need the dust for?

Big spell mage I'm missing some epics I have quest for priest but I'm missing some epic good dead rattle  cards too şike reckless experimenter

Keep him for now, he has seen play in some decks in HGG last week so you might see him used a bit more during next weeks.
Can help priest in control matchups when it comes to fatigue.

If you don't like control and/or priest it's safe dust, but you write you wanna use him, so i guess you don't really dislike either.
Play him a bit, you can still dust him later on.
