Falkenrath Gorger is a rare Creature — Vampire Berserker card from Shadows over Innistrad Remastered (SIR), collector number 153.
Each Vampire creature card you own that isn't on the battlefield has madness. The madness cost is equal to its mana cost. (If you discard a card with madness, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)
