Your opponents skip their upkeep steps.
At the beginning of your first upkeep each turn, you get an additional upkeep step after this step.

Choose one or both —
• Target opponent with more cards in hand than you reveals their hand. Choose a nonland card revealed this way. That player exiles it.
• Exile target nonland permanent if its controller controls more nonland permanents than you.
For as long as those cards remain exiled, their owner may play them. A spell cast this way costs {2} more to cast.

Equipped creature gets +3/+3.
Prevent all combat damage that would be dealt to equipped creature.
Equip {3}

Reach
As Celestial Principality enters the battlefield, choose a number.
Noncreature spells with mana value equal to the chosen number can't be cast.

{T}: Add {C}.
Civilized — {T}: Add {C}{C}. Activate only if you control an artifact, a creature, and an enchantment.

Whenever you cast a spell, if it isn't your main phase, create a 1/1 white Monk creature token, then creatures you control get +1/+1 until end of turn.

Legacy (You may play this side of this card only from your graveyard. Exile it if it would be put into a graveyard or not resolve.)
Shuffle any number of target cards in graveyards into their owners' libraries.
Scry 2, then you gain 3 life.

When Ch'aska Walla Captain enters the battlefield, if you cast it, you may return an enchantment card from your graveyard to the battlefield. When you do, you gain life equal to that enchantment's mana value.

As long as you control three or more creatures with the same name, Scouts and Wizards you control can't be blocked.
A deck can have any number of cards named Ch'aska Walla Chasqui.

Lifelink
Whenever you cast a noncreature spell, put a +1/+1 counter on Ch'aska Walla Vanguard.

Enchant creature you control
Enchanted creature gets +1/+1.
When enchanted creature dies, you may search your library for a creature card with mana value equal to enchanted creature's mana cost minus 1, put it onto the battlefield, and attach Chain of Command to it, then shuffle.

Chain of Decimation deals 4 damage to target creature, 3 damage to two other target creatures, 2 damage to three other target creatures and 1 damage to four other target creatures. (You can't cast Chain of Decimation unless it has ten targets.)

Chained Greatwolf enters the battlefield with a defender counter on it.
{3}{G}{G}, Remove a defender counter from Chained Greatwolf: Chained Greatwolf gets +5/+5 and gains trample until end of turn. Activate only during your turn.

Creatures entering or leaving the battlefield don't cause abilities to trigger. (This includes dying.)
Players can't sacrifice creatures to cast spells or activate abilities.

At the beginning of your upkeep, each opponent loses 1 life and you gain 1 life.

Whenever a creature an opponent controls becomes tapped, put a +1/+1 counter on Chalkira Duelist.

Whenever a permanent enters the battlefield 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.

{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 Reflections enters the battlefield, 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 the battlefield tapped.
When Chamber of Splendor enters the battlefield, 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.

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.

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