Fuel for the Cause (MBS 25) is a blue Instant from Mirrodin Besieged. It counters a target spell and then lets you proliferate, adding additional counters to any permanents or players that already have counters. This card enables counter-based synergies by both denying a spell and increasing existing counters on permanents or players.
