When Chamber of Penance enters the battlefield, exile target nonland permanent an opponent controls until Chamber of Penance leaves the battlefield.

Vigilance
Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)
When Champion of Destinies becomes renowned, you become the monarch.

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.)

Menace (This creature can't be blocked except by two or more creatures.)
Heroic — Whenever you cast a spell that targets Champion of Keranos, Champion of Keranos deals 2 damage to each opponent.

Flying
When Champion's Steed enters the battlefield, put a flying counter on target Avatar you control without flying.

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.)

Choose one —
• Destroy target artifact or enchantment.
• Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Double each number and amount of target instant or sorcery spell, activated ability, or triggered ability. Its controller may choose new targets for it. (Amounts are number words, X values, and “a” or “an” used as 1.)

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.)

When Chantwood Channeler enters the battlefield from your graveyard, it gains haste and creatures you control get +3/+3 and gain trample until end of turn.
{5}{G}{G}{G}, Sacrifice a creature: Return Chantwood Channeler from your graveyard to the battlefield. Activate only as a sorcery.

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.

Whenever you cast a spell, reveal the top card of your library. If a card that shares a card type with that spell was revealed this way, Chaos Tradewinder gains flying until end of turn.

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

Reach
When Chaparral Hunter enters the battlefield, if a permanent you controlled died this turn, draw a card and you gain 3 life.

When Chapel Defendant enters the battlefield, you gain 1 life for each Citizen you control.

Trample
Whenever Charging Cassowary deals combat damage to a player, you may cast a copy of an Adventure of a permanent you control.

Primal {G} (During your turn, you may cast this spell for {G} instead of playing a land.)
When Charging Nymph enters the battlefield, it gets +2/+0 and gains haste until end of turn.

Enchant creature
When Charmed Sleep enters the battlefield, tap enchanted creature.
Enchanted creature doesn't untap during its controller's untap step.

When Charming Marauder enters the battlefield, 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 the battlefield or if it would leave the battlefield.)

Draw three cards, then discard a card.

Reveal the top seven cards of your library. Starting with you, each player chooses a nonland card from among them that hasn't been chosen this way. Put the chosen cards into your hand and the rest on the bottom of your library in a random order.

[+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.
