^ That's how the Health is calculated.

The 10 daemons that are selected are your leader and the top nine daemons with the highest combined attack+defense stats. (If there are two or more daemons eligible for the 10th spot with the same total stats, like Fire Mistress and Water Mistress, one will be selected at random; it doesn't matter if one is higher in defense or something.) It does not matter if any of them are on your teams. The only daemon you have control over is your leader.
