This has been my pet deck the last couple months. I beat PChapin with it last month, which was awesome, and this month used it exclusively from Gold 1 all the way to Masters. I hit Masters at ranked 10 and had a 16-4 win rate in my last 20 matches.
The combination of life gain and aegis keeps you in the running until you can start slamming Svetya. Then it is often (but not always) GG.
Any deck that runs 4x Evenhanded Golem and 4x Svetya will always have my heart. If that sounds fun to you, you should try it out too.
