Valgavoth's Onslaught [Duskmourn: House of Horror Promos]

Set: Duskmourn: House of Horror Promos Type: Sorcery Rarity: Rare Cost: {X}{X}{G} Manifest dread X times, then put X +1/+1 counters on each of those creatures. (To manifest dread, look at the top two cards of your library, then put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it's a creature card.) Tyvar and the Wanderer were done running.
