Making a hero that can generate resources seems like an obvious design choice, and I'm sure we will see one soon.
The 15 heroes we have so far have an rough average of:
9 Threat Cost
2 Will Power
2 Attack
2 Defense
4 Health
What kind of stats would you sacrifice to get a hero that says "[This hero] generates one additional resource."
I think I would take an 11 Threat, 1 WP, 1 A, 1 D, 3 H.
Add text that says "Exhaust this hero to search your deck for one Song attachment" and I would add three threat.
