Unless you plan on playing Planeswalkers, Terminate is better than Hero's Downfall. Instead of Mizzium Mortars, I would just put in Lightning Bolt or Incinerate. Dictate of The Twin Gods is kinda expensive for a card that hurts you as well.

Hey. It seems like this might work, but I would definitely put in more lands and maybe some Rampant Growth to get your mana up, since you have so many expensive cards. Since most of your creatures have deathtouch already, you could get rid of Archetype of Finality. Maybe add another Visara. Also, maybe add Abrupt Decay and/or Putrefy instead of Hero's Downfall.
Also, I'd get rid of Shared Triumph and Honor of the Pure (or at least one of them) and put in Daru Warchief. He's an extra 2/3, makes most of your creatures cost one less, and gives an extra +0/+1 to your creatures for only 2 more mana. You don't need both Field Marshal and Archetype of Courage, so choose the one you like better. I would go with Field Marshal because his +1/+1 can stack. I might put in Worship since you have a creature based deck. Otherwise, Angel's Grace is an instant that does the same thing (reduces life to 1 instead of killing you). Dawn Charm is nice because it's so flexible. Hero of Bladehold is an awesome creature you could look at. You might want to think about adding more instants like Path to Exile or Holy Day or Riot Control or Divine Deflection, just as an extra defense.
Hey. I would get rid of the non-basic lands. Gaining two life on it's own isn't great, and you have a lot of cards that don't require a non-colored mana. Emeria is only good once you have seven lands that aren't Emeria, and you don't consistently get seven lands when you have 20 of them, so I don't think you can get seven plains very often when you'll only have 16. Also, I would get rid of spidersilk net. 2 mana for reach isn't great, and you have other creatures to help you block flying. I would put in another Darien, just cause I think he's awesome, but he is kinda expensive mana-wise. I might add another Brimaz because he's just that good. Oblivion Ring is always nice to have in a white deck.
That is an interesting difference. I feel like Deflecting Palm is a lot better, even though it can't defend your creatures.
This seems like an awesome idea. My problem is I don't feel like I'm experienced enough to be giving advice on other decks, so I rarely comment. Anyway, I saw a unicorn deck that I had to comment onhttp://www.mtgvault.com/gottie/decks/candy-mountain/and a Red/Green Dragon Deck that seemed interesting, although I couldn't give him any advice. If any more experienced players want to check it out and see if they can help, I'd appreciate it. http://www.mtgvault.com/rotawar/decks/rg-fatties/
Definitely a cool idea. I've always liked the dragon cards too, and just created my first dragon deck. I chose to do red/black, though, mostly because I wanted to include Terminate. I'm not sure how much help I can be, but I'm going to link this to a deck commenting page in hopes that some more experienced players will look at it and give you some advice.
I've never seen a unicorn deck before. It definitely seems like it would be a lot of fun to play with.
Thanks for the comment. I would add dual lands, but they are too expensive for my tastes, with the exception of guildgates, and I just don't enjoy playing with them (coming into play tapped as always seemed too high a price to pay).
