Cards in your hand have lifecycle {3}.
{2}{G}, Sacrifice four creatures: Create two tapped 4/4 green Chimera creature tokens.
Lifecycle {3} ({3}, Discard this card: Create two tapped 1/1 colorless Elemental creature tokens.)

If a red source you control would deal damage, it deals that much damage plus 1 instead.
I, II — Exile the top card of your library. If it's red or a Mountain, you may play that card this turn.
III — Return target red instant or sorcery card from your graveyard to your hand.

Trample
Whenever a creature you don't control dies, you gain 2 life.
Whenever you gain life, put that many +1/+1 counters on target creature you control.

Reveal the top five cards of your library. Put an artifact or sorcery card from among them into your hand and the rest on the bottom of your library in any order.
Reconstruct {3}{R} (You may cast this from your graveyard for its reconstruct cost reduced by the mana value of a permanent you sacrifice as you cast it this way. Then exile this.)

Vanishing 5
The High Prairies enters tapped.
{T}: Add one mana of any color.

Destroy all lands. For each land destroyed this way, its controller creates a colorless land token named Blasted Lands with “{T}: Add {C}.”

Target opponent may have The Highest Stakes deal 4 damage to them. If that player doesn't, you draw two cards.
Compose (Then if you cast this from your hand, exile it and create a Saga token with “r3—You may cast a copy of this card from exile without paying its mana cost.”)

Spirited (When this enters, you may activate one of its activated abilities without paying its cost.)
{3}, {T}: Create a colorless Equipment artifact token with “Equipped creature gets +1/+1” and equip {1}. Attach that token to a creature you control.

Flying
You pay {0} to cast your first spell each turn rather than its mana cost. If you cast a spell with {X} in its mana cost this way, X is 8.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
Audition for green. (Create a 1/1 Construct Actor creature token, a Scout Role giving 2/3 and vigilance, or a Warrior Role giving 3/2 and trample. Roles replace older ones.)
Creatures you control get +1/+0 and gain trample until end of turn.

{T}: Add {C}.
{2}, {T}: Prevent all combat damage target creature would deal this turn.

At the beginning of your upkeep, reveal the top two cards of your library. An opponent chooses one. Put the chosen card into your hand and exile the other.
{4}, {T}: Put a card exiled with The Knowledge Hub into its owner's hand.

Harvest (You may tap any number of creatures you control as you cast this spell. If you do, reduce this spell's mana cost by their total power.)
Create an X/X green Beast creature token. Each opponent creates three 1/1 white Citizen creature tokens.

The Last Sacred Gate enters tapped.
While you're searching your library, you may play The Last Sacred Gate from your library. (You may only do so during your turn and if you have a land play remaining.)
{T}: Add {C}.

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.)

{X}{G}: Put X +1/+1 counters on target noncreature, nonplaneswalker permanent you control. It becomes an Elemental creature with base power and toughness 0/0 in addition to its other types. (This effect lasts indefinitely.)

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.)

Creatures you control get +2/+0 until end of turn. Creatures you control with counters on them gain trample until end of turn.

{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 planeswalker you control is an Okus in addition to its other types.
[–1]: Search your library for a planeswalker card or an Aura card with enchant planeswalker, reveal it, and put it into your hand, then shuffle.
The Paragon of Haberdashery can be your commander. If it is, it's all colors.

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.

Indestructible
Spells you cast from your graveyard cost {6} less to cast.
Whenever you attack, you may cast any number of target cards from your graveyard this turn. If a spell or permanent that was cast this way would be put into a graveyard, exile it instead.
