Without Fall From Grace, the Heartless Alliance doesn’t really deserve a guide of its own. The general logic is that you almost always want (2) Heartless in Warriors (Pudge + 1), Knights (Abaddon + 1), and Hunters (Drow + 1). The additional Heartless is usually Necro because he also allows you to get the (2) Warlocks bonus along with the (2) Heartless bonus, which makes him an extremely efficient hero for one slot.

If you get the Fall from Grace item later in the game, there’s nothing too interesting you can do. You are already running a certain strategy. If it has humans and deals physical damage (most commonly Knights and Hunters), you get the item. If not – you don’t.

If you get Fall from Grace early in the game, however, you can unleash your creativity.
