Pay 2 life, Sacrifice a Clue: Draw a card.

Sunken Homestead enters tapped.
{T}: Add {B}.
{2}{B}: Until end of turn, Sunken Homestead becomes a 2/2 Zombie creature with “When this creature dies, return it to the battlefield.” Activate only if you're horrific.

Sunrise Ruins enters tapped.
{T}: Add {B}.
You may untap Sunrise Ruins during each other player's untap step. Whenever you do, you lose 1 life.

When Sunset Cliffs Patron enters, you may post a bounty on target creature. (Put a bounty counter on that creature. It has “When this creature dies, each opponent draws a card” as long as it has a bounty counter on it.)

Target creature gets +2/+0 until end of turn and gains “When this creature dies, return it to the battlefield tapped under its owner's control.”

As an additional cost to cast this spell, torment yourself. (You lose 3 life unless you discard a card or sacrifice a nonland permanent.)
Destroy target creature.

Return up to one target creature card and up to one target land card from your graveyard to your hand.

Swarming Midden enters tapped unless you control a basic Swamp.
{T}: Add {B}.
{1}{B}{B}: Swarming Midden becomes a 2/3 black Rat creature with menace until end of turn. It's still a land. Whenever it attacks this turn, create a 1/1 black Rat creature token with “This creature can't block.”

Target player reveals their hand. Exile a nonland card from it and put a secret counter on it. As long as that card remains exiled, that player may pay {2} any time they could cast a sorcery to put it into their hand.
{X}{B}{B}, Exile Swipe Secrets from your graveyard: Until end of turn, you may cast target card you exiled with a secret counter on it and mana value X without paying its mana cost.

Syndicate Sycophant can't block.
When a creature you control scavenges Syndicate Sycophant, you may search your library for a card named Syndicate Sycophant, reveal it, put it into your hand, then shuffle.
Scavenge {2}{B} ({2}{B}, Exile this card from your graveyard: Put a number of +1/+1 counters equal to this card's power on target creature. Scavenge only as a sorcery.)

Enchant creature
Enchanted creature has deathtouch and “{1}{B}: Regenerate this creature.”

Lifelink
Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)

At the beginning of each player's upkeep, put a darkness counter on target nonland permanent they control. That permanent is black for as long as it has a darkness counter on it. Then if there are five or more nonland permanents on the battlefield and they are all black, you may exile Tahiel, Elder Kalku and gain control of target creature or planeswalker.

Whenever a creature you control is dealt damage, it gains indestructible until end of turn. (If it survives.)

Enchant land
Enchanted land loses all land types, has “{T}: Add {C}”, and loses all other abilities.

If an opponent would gain life, that player loses that much life instead.

When Taken Away enters, target opponent reveals their hand. You choose a nonland card from it and exile that card until Taken Away leaves the battlefield. You may cast that card for as long as it remains exiled, and you may spend mana as though it were mana of any type to cast that spell.

Deathtouch
Breach (Whenever this deals combat damage to a player, you may have it become an Aura Curse until your next turn. Attach it to that player.)

[+2]: Up to one target creature gets -1/-1 until your next turn. Tap it. You may remove all counters from it.
[–2]: Destroy target creature with no counters on it.
[–10]: Each opponent's life total becomes equal to the number of creatures they control.

You may pay {2}{B}{B} and tap an untapped Pirate you control rather than pay this spell's mana cost.

Return target creature card from your graveyard to the battlefield.
Fabled {2}{B} (Then if you cast this for its fabled cost, put it onto the battlefield transformed attached to that creature.)

Destroy target creature with mana value X or less.

Each player sacrifices a creature.
Coalesce {5}{B} (You may cast this from your graveyard for {5}{B}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
