These are my personal suggestions for this deck.

Creatures: Archangel of Thune x4. Medomai the Ageless x4. Archon of the Triumvirate x4. Daxos of Meletis x2. Grand Abolisher x4. Jhessian Balmgiver x2. Soul Warden x4. Lyev Skyknight x2.Instants: Dramatic Rescue x2. Sphinx's Revelation x2.Enchantments: Unquestioned Authority x2. Aqueous Form x2.Sorceries: Ghostform x2.Lands: Temple of Enlightenment x4. Island x10. Plains x10.

This deck is not Azorius, but I do like you're suggestions for making my creatures unblockable. I do want Thassa, God of the Sea in this deck, instead of just making do with instants and sorceries and to kick up my devotion I'll use Aqueous Form as opposed to Unquestioned Authority (plus this is a modern deck!) for unblockability. Ghostform is not that great because they're one-offs and I've decided on using Venser, the Sojourner and Tamiyo, the Moon Sage to continue on my unblockable rampage. Sphinx's Revelation is kinda unnecessary and I don't want to detain anything for those other creatures. I might use Temple of Enlightenment(but definitely not four. Anyway, even though I threw out most of you're suggestions they were very good, thanks a lot!

Unfortunately the current modern format is a very fast paced format and I'm seeing a lot of 5 casting cost creatures. By turn 4 the game can be over if you're facing splinter twins or other tier 1 decks. I would suggest Aether Vials or Quick Silver amulets to speed up the process and more removal like path to exile or counter spell are a good way to get you into late game. Oblivion Ring is a very good cheap removal enchantment if your going for a budget.

Isn't AEther Vial banned?

@voromir I've decided I'll replace my Soul Warden with 2xAEther Vial and 2xPath to Exile, tell me if I should change these ratios. I don't want counter-spells because it only stops you from losing, not making you win. I'd like you to state how I'm going use the Quicksilver Amulet and I prefer Path to Exile as opposed to Oblivion Ring. Thanks a lot for the comment, it was very helpful!
