Flying
Whenever another creature you control enters, you may search your library for an instant or sorcery card with the same mana value as that creature, reveal it, put it into your hand, then shuffle.

Attacking Pirates and Rogues you control get +1/+0.
{2}{U}: Tap target creature an opponent controls.

When Lysene enters, you may search your library for a card with foretell, reveal it, put it into your hand, then shuffle. The next card you foretell this turn costs {0} to foretell.
Whenever you foretell a card or cast a foretold spell, Pirates and Rogues you control get +1/+0 until end of turn. Up to one target Pirate or Rogue you control can't be blocked this turn.

Spells you cast from anywhere other than your hand cost {1} less to cast.
At the beginning of combat on your turn, another target Pirate or Rogue you control gets +X/+0 and gains haste until end of turn, where X is the number of noncreature spells you've cast this turn. That creature can't be blocked this turn.

Flying, haste
Whenever Ma'Long deals combat damage to a player, draw a card, then add that much mana in any combination of {U} and/or {R}. Until end of turn, you don't lose this mana as steps and phases end.
Instant and sorcery cards in your hand have showcase. The showcase cost is equal to the card's mana cost plus {2}. (If you cast it for its showcase cost, create a 1/1 red Bard creature token that can't block and exile that card. Whenever the Bard attacks, you may cast a free copy of the exiled card.)

When Maaru, Tomb Guardian enters, create three Treasure tokens.
Each Treasure you control is an artifact creature with power and toughness each equal to the number of Treasures you control.

[+1]: Create a tapped colorless land token named Far-Off Lands with “{T}: Add one mana of any color.”
[–1]: Choose a color. Untap all lands you control that could produce that color.
[–6]: Draw a card for each differently named land you control.

Whenever you cast a spell, if it doesn't share a name with a permanent or a card in a graveyard, draw a card.

Archive 5 (As this enters, shuffle the top five cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you draw a card from the archived library, until end of turn, you may spend mana as though it were mana of any color to cast spells with the same name as that card and spells with that name can't be countered.

[+1]: Return a land you control to its owner's hand. Create a tapped colorless land token named Far-Off Lands with “{T}: Add one mana of any color.”
[–1]: Discard a card. Return to your hand a card from your graveyard that shares a color with that card or a color of mana it could produce.
[–3]: For each color pair, you may pay that mana. Create X X/X green and blue Elemental creature tokens, where X is the number of times you do.

First mate—Each nonland card in your starting deck is an instant or has flash. (If this card outside the game is your chosen first mate, you may swap it with a card in your opening hand.)
Flash
When Mable enters, you gain 2 life and draw a card.

Menace
Whenever Margarete or another creature you control dies, up to one target creature you control cackles. (Put a menace counter on it. If it already has menace, it deals 1 damage to each opponent instead.)
Once each turn, when Margarete or another creature you control with menace dies, you may torment each opponent. (They lose 3 life unless they discard a card or sacrifice a nonland permanent.)

If Madame Beatrice would leave the battlefield, exile her instead.
Whenever one or more creatures you control deal combat damage to a player, that player reveals their hand. You may cast a card from their hand without paying its mana cost.

Whenever an opponent activates an ability of a permanent, if it isn't a mana ability, you gain 1 life and create a Gold token. (It's an artifact with “Sacrifice this artifact: Add one mana of any color.”)

Haste
Whenever you cast a spell, if you spent mana to cast it, draw a card. Then you may cast a card with mana value less than that spell's mana value from your hand without paying its mana cost.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I, II — Exile up to one target creature you control. At the beginning of your next end step, return it to the battlefield.
III — Until end of turn, if a creature entering the battlefield causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.
​

Haste
When Magmatic Violator enters, target opponent sacrifices a creature.
At the beginning of the end step, sacrifice Magmatic Violator.

You may put a creature or planeswalker card from your hand onto the battlefield. If it's a creature, it gains haste and indestructible. Return it to your hand at the beginning of your next end step.

Prowess
When Magus Aspirant enters, you may search your library for an instant or sorcery card, reveal it, put it into your hand, then shuffle.

At the beginning of your upkeep, if five or more instant and/or sorcery cards are in your graveyard, return target instant or sorcery card at random from your graveyard to your hand.

Whenever Mahara Vanguard attacks, Soldiers you control get +1/+0 and gain menace until end of turn.

• Return up to two target creature cards from your graveyard to your hand.
• Return up to two target enchantment cards from your graveyard to your hand.
• Return up to two target artifact cards from your graveyard to your hand.

Transcend (Activate as a sorcery to gain the next type and a +1/+1 counter.)
When Mahara enters, if you cast them, destroy all other creatures.
{W}{B}: Angel — You gain 4 life and amass Soldiers 4. (Put four +1/+1 counters on an Army you control. It's also a Soldier. If you don't control one, create an 0/0 black Soldier Army creature token first.)
{5}{W}{B}: Elder — Amass Soldiers 20.

Indestructible
Whenever this creature enters or transforms into Mahara, recruit. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)
At the beginning of your end step, if you control four or more creatures, transform Mahara.

Whenever you cast a spell with mana value 4 or greater, create a Treasure token. If that spell's mana value is 6 or greater, draw a card. If that spell's mana value is 8 or greater, Main Role Maiden deals 4 damage to each creature and planeswalker you don't control.
