Get your hexproof creatures out and stack your enchatments, thats the name of the game. Mana should not be an issue with 8 dual lands and 4 Mana Confluence. You can generate life with the Hopeful Eidolon, and Unflinching Courage. Courser of Kruphix, Boon Satyr and Hopeful Eidolon are enchantments with bodies to help Ethereal Armor.

With all the enchantments Eidolon of Blossoms can net you insane card draw.

So this is kind of a Voltron deck, So I named it after the planet Arus which is the world Voltron comes from in the series.
