This card is very powerful, when added to the combo of Will to Survive, True Survivor and 2x Resourceful.
What the combo does: Play Will to Survive and commit 2x Resourceful on any test to recover True Survivor and Will to Survive. Next turn play True Survivor to recover 2x Resourceful and any other skill.
You can repeat this as often as you want until you run out of ressources, which happens pretty fast at a total cost of 7 (4 + 3). Enter On Your Own: It reduces the total cost to 3!
I've only seen one deck (my own) that could pull of the old combo, but with reduced costs nearly every survivor should be able to pull it off. Maybe not Wendy because her Abandoned and Alone weakness destroys many survivor discard pile recurring.
You can use any version of Emergency Cache and Take Heart to gain more ressources. I think testless actions are very strong as you potentially avoid many bad icons that might hurt you or add doom, so even taking the "gain 1 ressource" action can be a good idea to keep the combo going.
