Duskmourn: House of Horror

Coordinated Clobbering | Sorcery | | Tap one or two target untapped creatures you control. They each deal damage equal to their power to target creature an opponent controls. | Fajareka Setiawan

Insidious Fungus | Creature | Fungus | {2}, Sacrifice Insidious Fungus: Choose one — • Destroy target artifact. • Destroy target enchantment. • Draw a card. Then you may put a land card from your hand onto the battlefield tapped. | Slawomir Maniak

Patchwork Beastie | Artifact Creature | Beast | Delirium — Patchwork Beastie can't attack or block unless there are four or more card types among cards in your graveyard. At the beginning of your upkeep, you may mill a card. (You may put the top card of your library into your graveyard.) | John Tedrick

Valgavoth's Onslaught | Sorcery | | 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.) | Lie Setiawan
