When 1-ST Thankless Companion enters, draw a card.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
Audition for white. (Create a 1/1 Construct Actor creature token, a Scout Role giving 2/3 and vigilance, or a Cleric Role giving 2/2 and lifelink. Roles replace older ones.)
Distribute two +1/+1 counters among creatures you control.
​

Each other Okus planeswalker you control enters with two additional loyalty counters on it.
[–2]: Create a 2/2 white Knight creature token with vigilance.

If this spell targets a card that was put into a graveyard from the battlefield this turn, you may pay {W} rather that pay its mana cost, and cast it as though it had flash.
Return target creature card from your graveyard to the battlefield.

Vigilance
Cadence (Whenever you cast a spell, if its mana value is greater than this creature's power, put a +1/+1 counter on this creature.)

Flying

{1}, Sacrifice Aberrant Apostle: Choose one. This ability costs {1} less to activate as long as Aberrant Apostle entered this turn.
• Destroy target artifact.
• Destroy target enchantment.
• Exile target card from a graveyard.

Whenever you cast a noncreature spell, put a +1/+1 counter on Abjuration Savant. It gains flying until end of turn.
When Abjuration Savant dies, you gain life equal to its toughness.

At the beginning of your end step, you may pay {W}. If you do, exile target creature you control, then return that card to the battlefield under your control.

Destroy target creature with power 4 or greater. You gain 2 life.

Exile any number of target cards in exile. (They become new objects that have just been exiled.)
Draw a card.

Flying
Whenever Acabo, the Fabled Falcon attacks, you choose how up to one target creature an opponent controls blocks this turn.

After a player chooses two or more modes while casting a spell, you may pick one of those modes. That mode is no longer chosen. (That player doesn't pick targets or pay costs related to that mode. If a mode is chosen multiple times, only one instance of that mode is lost.)

Exile target creature or planeswalker and up to one target card from its controller's graveyard.

Enchant creature
Enchanted creature gets +2/+2. Other creatures you control get +1/+1.

Flying
{2}{W}, Exile a non-Spirit creature card from your graveyard: Create a 1/1 white Spirit creature token with flying.

Invigorate 5. (Choose a creature with the least power among creatures you control and put five +1/+1 counters on it.)

Exile target creature. At the beginning of the next end step, return that card to the battlefield under its owner's control with your choice of X counters on it from among +1/+1, flying, first strike, lifelink, or vigilance.

Lifelink
Converge — When Adapted Explorer enters, it deals X damage to up to one target tapped creature, where X is the number of colors of mana spent to cast it.

Whenever Adept Lieutenant attacks, create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)
{1}, Sacrifice an Idol: Put a +1/+1 counter on Adept Lieutenant.

Choose one —
• Destroy target artifact.
• Destroy target enchantment.
• Tap target creature and put two stun counters on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)

Extort (Whenever you cast a spell, you may pay {W/B}. If you do, each opponent loses 1 life and you gain that much life.)
Creatures can't attack you or planeswalkers you control unless their controller pays {2} for each of those creatures.

Whenever you cast an Adventure spell, put a +1/+1 counter on Adventurer Extraordinaire.

Trial 4 (As you cast this spell, an opponent of your choice may pay 4 life. If they don't, they fail the trial.)
Create a 1/1 white Cleric creature token. If the trial was failed, create three of those tokens instead.

Flying
Aedryd, Spectral Liege's power and toughness are each equal to the number of creatures you control.
{2}{W/U}: Another target creature you control gains flying until end of turn. When that creature leaves the battlefield this turn, create a 1/1 white Spirit creature token with flying.
