Grim Affliction puts a -1/-1 counter on any target creature and then proliferates — two meaningful board actions stapled to a single three-mana instant. In The Scorpion God decks, that's a draw trigger and a doubling of every counter on every permanent you care about, all at instant speed.

The Scorpion God
The Scorpion God draws a card whenever a creature with a -1/-1 counter dies, so Grim Affliction is doing double duty: placing the counter that primes the draw trigger, then proliferating to push other creatures closer to lethal.

Hapatra, Vizier of Poisons
Hapatra, Vizier of Poisons creates a Snake token every time you put a -1/-1 counter on a creature, and Grim Affliction both places that initial counter and proliferates to stack more counters across the board — each additional counter is another token trigger waiting to happen.

Massacre Girl, Known Killer
Massacre Girl, Known Killer gives all your spells and abilities that put -1/-1 counters on creatures the casualty of also placing a counter on any other creature, and Grim Affliction feeds that engine while the proliferate clause threatens to drag everything into zero-toughness range simultaneously.

The Reaper, King No More
The Reaper, King No More rewards stacking -1/-1 counters as a win condition, and Grim Affliction's proliferate clause turns a single counter placement into a board-wide attrition push that accelerates the game plan by a full turn.

Skithiryx, the Blight Dragon
Skithiryx, the Blight Dragon runs an infect package where every poison counter matters, and Grim Affliction's proliferate clause converts a modest board state into a closing threat by ticking opponents' poison totals up after Skithiryx connects.

In Commander, Grim Affliction is a role-player rather than a staple — it earns its slot in dedicated -1/-1 counter and proliferate builds but has no business in a generic black deck. Pauper is its most competitive home: proliferate effects are scarce at common, and the instant speed matters against creature-heavy fields. In Legacy, Modern, and Vintage, the card is legal but never played — three mana for a conditional -1/-1 counter is far too slow against the threats those formats present, and better proliferate options exist.
