• Type: Action
• Cost: 5
• Effect: Choose one — (A) Gain a card from the trash, putting it on top of your deck. (B) Trash an Action from your hand, gain a card costing exactly 3 more.

Two-mode trash interaction: trash-pile recovery + +3-cost upgrader. Stronger than Remodel for Action upgrade. A-tier.

Opening: $5 Graverobber. Initially use mode B — trash a 4-cost Action, gain a 7-cost.

Midgame: Trash-pile fills (Spoils, Hunting Grounds), pivot to mode A retrieval.

Endgame: Mode B for engine-piece upgrades to 7-cost Actions. Mode A retrieval for finishers.

• Fortress: Graverobber retrieves Fortress from trash to hand (no trash trigger).
• Procession: 2× Graverobber = 2 retrievals.
• Remodel: Graverobber's +3 cost > Remodel's +2.
• Throne: 2× Graverobber.

• Stocked trash: Fortress / Spoils / Hunting Grounds / Artisan.
• Procession / Count: Trash-pile chains.
• Action-heavy: Mode B targets.
• Fortress loop: Retrieval method.
• Gardens: Mass gain VP.

• Empty trash: Mode A dead.
• Action-light: Mode B dead.
• Pre-thinned deck: Both modes weak.
• $5 scarce: Few buys.

The trick is curating the trash pile. Chapel / Procession / Count creates targets, Graverobber retrieves.

Mode B's +3 cost upgrade jumps engine pieces 5 → 8 (Action though, so 7-cost cap practically).

Procession + Graverobber = 2 plays + trash + 6-cost gain. Recursive trash-engine peak.
