While Satan's def down won't stack with Amon's yet, the additional -10% dark res down from awakening will still factor in, meaning -35% def down with Amon and Awakened Satan. With Sniper Shot (or Dark Ama or Lu Bu), you'll still be hitting that -50% def down.
Feeling Vine is still a good factor in dark teams as well, simply because you can use her with Anubis. Though not sure how much a difference her low stats will impact future content.
