Double strike
Motley — As long as there are five or more names among nonland permanents you control, Champion of Blades has vigilance, trample, and haste.

Whenever you sacrifice a permanent, Champion of Foibles becomes a Demon with base power and toughness 6/6, flying, and trample until end of turn.
{3}{B}: Judge target creature you control. Activate only as a sorcery. (Honor it by putting a +1/+1 counter on it or condemn it by sacrificing it to draw a card.)

As long as Champion of Ideals has one or more +1/+1 counters on it, it's an Angel with base power and toughness 4/4, flying, vigilance, and lifelink.
{3}{G}: Judge target creature you control. Activate only as a sorcery. (Honor it by putting a +1/+1 counter on it or condemn it by sacrificing it to draw a card.)

Lifelink, trample
Champion of Stilthorpe's power and toughness are each equal to the number of Citizens and/or Peasants you control.

Lifelink
Instant and sorcery spells you control have lifelink.
{2}{R}{W}: Copy target instant or sorcery spell. You may choose new targets for the copy.

Each opponent sacrifices a creature that dealt damage this turn. You gain 2 life, then abound. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)

Menace
Creatures you control with mana value 1 get +2/+0 and have menace.

Whenever you cast a noncreature spell, if you control exactly one creature, copy that spell. You may choose new targets for the copies. (If it's a permanent, it resolves as a token.)

Search your library for three differently named noncreature, nonland cards with mana value 3 or less not named Chaos Is Your Redemption and exile them, then shuffle. If you exile three cards this way, cast one at random without paying its mana cost. Then shuffle the rest into your library.

(Activate each submodule once as a sorcery. When this enters, activate one submodule for free.)
{2}{R}: Anarchy
Exile the top three cards of your library. You may cast up to one enchantment spell and play up to one other card exiled this way until the end of your next turn.
{2}{B}: Despair
Each cursed opponent sacrifices a creature.
{1}{B}{R}: Strife
Chaos Module gains “At the beginning of your end step, each cursed opponent loses life equal to the number of Curses attached to them.”

When Chaotic Pupil enters, harmonize twice. (To harmonize, trigger up to one harmony of a permanent you control.)
Harmony — Draw a card, then discard a card.

Once each turn, when a creature you control attacks alone, you may untap target attacking creature. After this combat, there's an additional combat step.

When Charming Marauder enters, you may destroy target artifact or enchantment.
Recite {2}{W} (You may cast this creature from your graveyard for its recite cost. If you do, exile it when it enters or if it would leave the battlefield.)

Look at the top three cards of your library. You may exile one that doesn't share a mana value with any cards exiled with Chart the Vast. Put the rest on the bottom of your library. If you exiled a card, repeat this process. Otherwise, put all cards exiled this way into your hand.

Flying, haste
Whenever Cheng attacks, look at the top six cards of your library. You may reveal a creature card from among them and put it into your hand. If it's a Dragon, put it onto the battlefield tapped and attacking instead. Put the rest on the bottom of your library in a random order.

Whenever Chi Lee attacks, you may discard a card. If you do, create a 4/4 black Demon creature token with “Whenever this creature deals combat damage to a player, return target card from your graveyard to your hand.”

[+1]: Return up to one target Aura card from a graveyard or on the battlefield to its owner's hand.
[–2]: Sacrifice an enchantment. If you do, return target enchantment card from your graveyard to the battlefield.
[–6]: Draw three cards. Until end of turn, you may cast enchantment spells without paying their mana costs.

Whenever a card is put into a graveyard from anywhere, put a +1/+1 counter on Chief Striking Dawn.

{1}, Sacrifice a creature: Put a +1/+1 counter on Chitterrax, then each opponent loses 1 life and you gain 1 life.

As an additional cost to cast this spell, discard a card.
Create three 1/1 black Spirit creature tokens with flying.

Flash
Flying, lifelink, deathtouch
