Whenever a permanent enters under an opponent's control, reveal the top card of your library. If it's a permanent card that shares a type with that permanent, you may put it onto the battlefield. Otherwise, put it on the bottom of your library.

Haste
When Challenging Pupil enters, conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

{T}: Add {C}.
{T}: Add one mana of any color among creatures and planeswalkers you control.
{T}: Target player may gain control of target permanent you own. (That player may choose not to.)

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

When Chamber of Reflections enters, draw a card, then choose a legendary card name.
Permanents you control with the chosen name have hexproof and the “legend rule” doesn't apply to them.

Chamber of Splendor enters tapped.
When Chamber of Splendor enters, you may pay {1}. If you do, create a Treasure token. (It's an artifact with “{T}, Sacrifice this artifact: Add one mana of any color.”)
{T}: Add {C}.

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.

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.

First strike, haste
Wanderlust — At the beginning of combat on each of your turns, if you control four or more differently named lands, you may pay {1}{R}. If you do, create a 4/4 red Dragon creature token with flying and haste. Exile that token at end of combat.

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

Whenever you cast a spell during an opponent's turn, put a +1/+1 counter on Champion of the Fae.

Flash
Flying
When Champion of the Provinces enters, return any number of other permanents you control to their owner's hands.

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.

Flying
When Champion's Steed enters, 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.)

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

Target creature gets +2/-2 until end of turn. (Then exile this card. You may cast the artifact later from exile.)

Target creature gets -1/-2 until end of turn.
Target creature gets +2/+1 until end of turn.

As an additional cost to cast this spell, sacrifice a creature or planeswalker.
Destroy target creature or planeswalker.

Exile target creature. That creature's controller creates a 1/1 white Soldier creature token, then judges that token. (They honor it by putting a +1/+1 counter on it or condemn it by sacrificing it to draw a card.)

Whenever a permanent you control transforms, draw a card.

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