Choking Fumes⁣ - Mirrodin Besieged⁣ (Uncommon)⁣ [4]

Choking Fumes is an instant that places a -1/-1 counter on each attacking creature, making it effective for weakening opponents' forces during combat. This card is valuable in decks that focus on controlling the board and can help stall aggressive strategies. However, it requires careful timing, as it only affects creatures that are currently attacking.
