The Torment of Gollum
Coercion with a rider is a familiar shape: black has been paying a little extra to turn Duress into targeted discard where you pick the card since the earliest sets. What distinguishes this one is the second clause, which spends the same card on board presence rather than a second point of information. Amass lets targeted discard double as a creature investment, so the turn you strip the best nonland card from an opponent's hand you also leave two +1/+1 counters on an Army, growing a token you may not have had before. That pairing is rare: disruption and development usually compete for the same mana, and stapling them together means neither half comes out premium. The discard is unconditional and hits any nonland card, which keeps it live against control and combo, but at four mana the body it builds is modest and the Orc typing only matters where an Orc payoff exists. The design logic is aggro-attrition: a deck that wants to punch through a defensive hand while still committing to the board, trading raw efficiency for the ability to do two jobs on one card. And it answers the classic weakness of hand disruption, that a topdecked answer refills whatever you took, by leaving something behind on the battlefield that a fresh draw cannot undo.
