Whenever you cast an enchantment spell, you may put target creature on the bottom of its owner's library.

Rather than pay the mana cost for a spell, its controller may discard a card that shares a color with that spell.
Whenever an opponent casts a spell, counter that spell unless they pay 5 life.

Hexproof
Whenever an opponent casts a spell or draws a card, draw a card.

Convoke (Each creature you tap while casting this spell pays for {1} or one mana of that creature's color.)
Protection from noncreatures
When The Magistrate enters, judge each creature that convoked it. (Honor it by putting a +1/+1 counter on it or condemn it by sacrificing it to draw a card.)

Haste
Whenever The Marquess Devonport attacks, it deals 2 damage to you.
Attain {5}{R} ({5}{R}: Transform this. Spend at least three colors of mana to activate this, and only as a sorcery.)

Target player discards a card and gets a poison counter.
Coalesce {4}{B}{B} (You may cast this from your graveyard for {4}{B}{B}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

As The Mistake enters, choose a card name.
Activated abilities of sources with the chosen name can't be activated unless they're mana abilities.
Unveil {5} ({5}: Transform this. Unveil only as a sorcery.)

When The Moon Rises enters, exile all opponent's graveyards.
At the beginning of your upkeep, each opponent loses 1 life.

The Mythical Zhiwu enters with four +1/+1 counters on it.
{1}, Remove a +1/+1 counter from a creature you control: Target creature gets -1/-1 until end of turn. Activate only as a sorcery.
{1}, Remove a +1/+1 counter from a creature you control: Each opponent loses 1 life and you gain 1 life.

[–1]: Exile the top three cards of your library. Until end of turn, you may play cards exiled with this permanent.
[–3]: Create a 5/5 Archon creature token that's all colors and has flying and “When this creature enters, it deals 5 damage to any target.”

{T}: Add {C}.
{2}, {T}: Choose a color, then choose one —
• Add one mana of that color for each token you control.
• Add one mana of that color for each permanent you control with one or more counters on it.

Whenever equipped creature dies, put a doom counter on The Pactbinder's Cane. Then if it has six or more doom counters on it, you may search your hand, library, and graveyard for a creature card with mana value 5 or greater, put it onto the battlefield, then shuffle. If you do, exile The Pactbinder's Cane.
Equipped creature gets +1/+0.
Equip {1}

Each player chooses a nonbasic card name, then searches each of their opponents' graveyards, hands, and libraries for any number of cards with the chosen name and exiles them. Each player shuffles, then draws a card for each card exiled from their hand this way.

Creatures you control have trample, haste, and hexproof.
{2}{G}{G}: Create a 2/2 white Cat creature token.

This spell can't be countered.
Whenever a creature you control with power 5 or greater attacks alone, it deals damage equal to its power to each opponent and to each other creature and planeswalker.

When The Raven Queen of Fretport enters, put a -1/-1 counter on each of any number of target creatures.
{2}{U}{B}: Proliferate. (Choose any number of permanents and/or players with counters on them, then give each another counter of each kind already there.)

Whenever The Resting Place deals combat damage to a player, you may return a creature card with mana value 3 or less from your graveyard to the battlefield.
Crew 2

{T}: The next time you would draw a card this turn, instead search your library for a card, put it into your hand, then shuffle. Activate only as a sorcery.

Flying
Whenever one or more other creatures die for the first time each turn, journey. (To journey, exile the top card of your library face up. Whenever a creature you control deals combat damage to an opponent, put a journeyed card you own into your hand.)

Vanguard — Whenever a creature you control attacks alone, gain control of target nonland permanent for as long as you control The Rocket Gang Strikes!.

Equipped creature gets +2/+1. As long as it's your turn, it has deathtouch and lifelink.

Equip {3}

Siphon (Each -1/-1 counter you put on your creatures up to their remaining toughness while casting this pays for {1}.)

Trample
Creatures you control have “{T}: This creature deals 1 damage to each opponent. Activate only as a sorcery.”
At the beginning of combat on your turn, if an opponent lost 4 or more life this turn, you may have The Shadowstaff become an artifact creature until end of turn.

Trample
When The Shepherd of Nowhere enters, each player sacrifices each other nontoken creature they control.
Whenever another nontoken creature you control dies, create a token that's a copy of that creature.

At the beginning of your upkeep, you lose 1 life, then reveal the top card of your library. You lose life equal to its mana value unless it is a creature card. Put that card into your hand.
