Pyke

Legend · Passive1 Energy, Exhaust: Return a friendly unit at a battlefield to its owner's hand. Play a Gold gear token exhausted. (It has "Reaction[Reaction] — Kill this, Exhaust: Add[Add] [C].")

Pyke strikes twice. Bloodharbor Ripper returns a unit from a battlefield to your hand — and replayed, its "when you play me" fires again — so his trials teach you which unit to bring home, and which fight to bait first.
