This creates a loop and is a fantastic card. It is presently probably the best card in the drowned city cycle.
Basically survivors already have cards that like to be in the discard pile. Improvised shield, winging it, improvised weapon, moonstone, glimmer of hope, etc.
Gift of Nodens lets you retrieve good skills (i.e., resourceful) and put cards that want to be in the discard into the discard. By using this pretty much exclusively with resourceful, you basically guarantee that you both keep resourceful going in your deck (and keep survivor assets that got tossed in your hand) while setting up these "from the discard pile" effects.
