How many miracles have you got? You could perhaps try to make a deck based on aether/light using dimshields, sanctuaries, miracles to keep alive, and phase dragons for your attackers; they'll get the job done slowly but surely. If you've got shards of divinity or wisdom you could use those as well. If you haven't got all those rares (and I'm guessing you won't have too many of them yet) you can just use any you might have and see if that works out for you. Upped sundials would also work well in such a deck if you've got any.
You could also try using a firefly queen / hope deck, which has the advantage that you won't be relying on any rares, and the number of different cards you need to get at the same time is kept to a minimum (queen + hope, rather than RoL + fractal + hope or whatever)
Another neat one I've seen is deja vu luciferin hope, which can be effective since each deja vu can potentially make two creatures, and then luciferin is essentially twice as effective over something like photon.
You could also try searching the forum for firestall, using fire and light, but you'll need 2 or 3 fahrenheits to make the best version. You can do it without them, but it's not as good.
Another light/aether deck you could try is PU dragons. Use light dragons, parallel universes, and whatever other stuff to keep you alive, maybe sanctuaries or dimshields or lightnings. (or miracles if you've got them)
If you have a couple vampire stilettos, try a crusader / vampire stiletto deck. A darkness mark to cast the stilettos plus maybe one or two other cards like steal or nightmare, and possibly a few pendulums depending how much of that stuff you use, and then your crusaders and a few other cards to fit your style. If you haven't got vampire stilettos, you could try something a little more unconventional, like hammers or short bows, and then use an appropriate mark for the bonus, and a few cards of the mark you choose for it, like momentum, shockwave, fog shield, or earthquake.
