GET ALL 4 DUSKMOURN: HOUSE OF HORROR COMMANDER DECKSSee the future and cast miracles with Miracle Worker, fill your graveyard and reanimate monsters with Death Toll, cast tricky instants and mysterious face-down cards with Jump Scare!, or control monstrosities and make your opponents pay with Endless Punishment
By itself, this is a Turn 3 win with no need for Turn 1 acceleration (unlike the Heliod, Sun-Crowned combos, for example) and only requiring two cards that are each quite versatile, making it more compact and modular than any other creature combo in these colours
But in this case, we get an additional +1/+1 on the body, we get to untap her whenever we cast a legendary spell, allowing us to use it again, and the flip side is the unholy union of Phyrexian Obliterator and Mindleech Mass
Just make sure there's always at least one copy of Guilty Conscience and one copy of Sinking Feeling on the battlefield at all times, because Copy Enchantment can't produce more without drawing from a surviving specimen
