Brg out moon n sun dragon out faster

Is there any way to get these guys out faster? I ned one of these syn in the graveyard so i can keep doing syn summon. Problem is i can brg out one and not the other. i try usingthat trzp card that discard crad in extra deck but that only works for fusion. Any help?

You don't really need both of them out at the same time. to be honest. If you want you can use Instant Fusion along with Limit Reverse to get both of them out.
