Bulwark paired with Dusty’s legendary and an SE team is awesome and entertaining. I have mine runed for damage and she races out and bellyflops her way to victory more often than not.
Dragon Slayer is a hard counter to Bone and Void, but while Void is still useful it isn’t because of his energy drain and almost no one is using Bone anymore. Otherwise she is ok as a tank but not amazing. I know everyone is using her for SE lines.
Angel Dragon can be awfully handy in Expo. His buff is handy and his heal and revive are awfully useful. I’ve also used him to decent effect against a few of the insta-Corgi’s.
Huntress does decent damage but Archer is better overall. I pull her out for Crypt.
I know a few folks who use Tomb Angel to good effect. Her stun has potential and I’ve faced a handful of good ones.
The rest...yeah, not all that useful.
