You missed out with necromancer. Arguably better than Dragoon, at least in the defense department. Being able to draw all attacks onto a wraith is really nice considering decoy bunker usually only draws some attacks. Also, you can skill wraith to auto incarnate when damage is not taken to the necromancer during a turn or when a wraith is dismissed, by knocking it out or sacrificing it for buff/debuff/healing/attack.
