Looks good to me.
What are the rules for flipping a card you control face up, again? Can you just do it on your turn for free?
Essentially, yeah. Shining Dawn will only be relevant when the enemy starts designing cards we don't want to let remain face down, and they haven't done so yet. (Honestly, they'd find it more useful then we would, it'd let them trigger the BFG when they wanted it to flip instead of having it bounce their big monsters out when they deployed them.)
Anyway, since no one's said otherwise, I'll call the Dragon's Graveyard.
My deck will be 6x Big Friendly Ghosts, 6x Wooly, 6x Mystery Ghosts, 5x Clover Fairies, 6x Solo Star Powers, 5x Hypersummons, 4x Summer Star Maidens, 1x Broomstick Witch, 1x Thorn Ward.
I'll either end up beating them to death normally or dropping a megamonster with a Hypersummon (preferably either the Broomstick Witch so nothing they have can block it or the Thorn Ward so it's a megamonster that bounces damage back at them). This is a variant of the tactic I've used in my last two games, so maybe they've finally countered it, but I'm going to keep using it until it stops working. I did completely drop the board wipes this time, which might backfire, but I've barely used them so far so we'll see.
