Azorius rules!!

The Azorius Guild and their Return to Ravnica ability of detain is also an excellent style of game play. Once again, it focuses on controlling the game rather then aggressive attacking strategies. 

Unlike other blue decks, my azorius deck has plenty of creatures in it to make use of the detain ability. 

 Azorius Arrester can begin detaining early on in the game, I run with 4 Lyev Skynights as my main detain soldiers, Azorius Justicar are also a worthy option as they can detain 2 creatures when they enter the Battlefield. Soulsworn spirit can detain and is unblockable. New Prahv Guildmage is a cheap hitter early in the game, but his detain ability is rather expensive. Later in the game Archon of the Triumvirate does a great job of detaining 2 permanents an opponent controls!!

To aid my creatures, I also run with Inaction Injunction and Martial Law which is a key enchantment in my deck.

To allow me to get the best out of my creatures with the detain ability, I have used cards such as Restoration Angel, Deadeye Navigator, Nephalia Smuggler and ghostly flicker. These creatures and spells allow my detain creatures to be exiled and then returned to the battlefield. Therefore they can detain again.

I use dramatic rescue and Faerie Imposter to return cards like Restoration Angel back to my hand, to allow the detain ability to be carried out yet again.

Arrest and detention sphere remove/neutralize threats from the battlefield.

I use cards such as Syncopate, Judges Familiar, Isperia, Supreme Judge to help control. If all goes wrong and I am being overwhelmed, Supreme Verdict is there to even out the playing field. Azor Elocutors provide a great distraction, whilst Palisade Giant can take some serious heat!

Again Syncopate artwork is awesome......

If all goes well......Azorius law and order will prevail!
