All about the Flavor.

End of the World (wipe & threaten to wipe the board many, many times). Contains many of the splashy big-effect Angels, sub theme of indestructible to survive the board wipes. Intentionally light on the exile boardwipes to make good on the indestructible and recursion/reanimation elements.

Avacyn, Angel of Hope is the current general. Expensive, but allows all my guys to survive the destruction-based boardwipes.
