White Nights

This is a simple Time and Shadow Nightfall deck, that tries to set up defense with Lunar Magus and Duskwalker before sticking the opponent with Nyctophobia off Miris Nightshade, or attacking up top with Umbren Reaper.

Key interactions include using Dark Return or Vara's Intervention to get back Miris and reset her ultimate ability, so you can stack extra curses on the opponent. Also, Baying Serasaur can get multiple triggers in a turn if it is Nightfall, and then you use Return on a Piercing Grief in the Void. (Return counts as drawing a card, then Destiny on the Grief gets you another card.)

I find the deck a lot of fun but it seems to be missing that last bit of gas to close out games. The top end is mostly experimenting with Azindel's Gift (to undo the extra cards we feed our opponent with Nightfall) and/or Encroaching Darkness (probably better overall but is very slow.)
