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

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
Flash
I — Draw three cards.
II, III — You may cast a spell with mana value less than or equal to the number of lore counters on The Infinite Calls to Marva from your hand without paying its mana cost.

First strike, trample
Death knell — Return a permanent card with mana value less than X from your graveyard to the battlefield, where X is the mana value of the last creature that died this turn. (As a creature you control dies, trigger one death knell of that creature or another permanent you control.)

When The Lonely Prophet enters, exile a card you own from outside the game face down.
Whenever The Lonely Prophet deals combat damage, put the exiled card into your hand.

{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.)

When The Raven Queen of Fretport enters, put a -1/-1 counter on each of any number of target creatures.
{2}{U}{B}: Proliferate. (Choose any number of permanents and/or players with counters on them, then give each another counter of each kind already there.)

Menace
Whenever you cast a spell from your graveyard, The Selhoff Twins deals damage equal to that spell's mana value to any target. Then copy that spell. You may choose new targets for the copy. (A copy of a permanent spell becomes a token.)

Primal {5}{W}{B} (During your turn, you may cast this spell for {5}{W}{B} instead of playing a land.)
Destroy all creatures. If this spell was cast for its primal cost, for each player, put up to one creature card from that player's graveyard onto the battlefield under your control.

Deathtouch, lifelink
At the beginning of combat on your turn, for each creature your opponents control, you may tap an untapped creature you control. If you do, those creatures fight each other.

Flying, menace, trample
When The Wickerscreech of Gatstaf dies, destroy target nonland permanent an opponent controls.
Foreshadow {13}. This costs {1} less for each nonland card in your graveyard. (You may cast this spell for its foreshadow cost. If you do, also trigger its “dies” abilities when it enters.)

When Theurgist of the Depths enters, for each card type, you may exile a card of that type from your graveyard. Target opponent separates those cards into two piles. Put all cards from the pile of your choice into your hand.
Recite {B}{G}{U} (You may cast this creature from your graveyard for its recite cost. If you do, exile it when it enters or if it would leave the battlefield.)

Flying
When Thief of Mortals deals combat damage to a player, as long as you control Thief of Mortals, gain control of target nonland permanent that player controls, and that permanent doesn't untap during its controller's untap step. Tap it.
At the beginning of each end step, if you control five or more permanents you don't own, you win the game.

Primal {5}{R}{W} (During your turn, you may cast this spell for {5}{R}{W} instead of playing a land.)
Until end of turn, permanents you control gain indestructible and permanents you don't control lose indestructible. Then if if this spell was cast for its primal cost, destroy all nonland permanents.

Whenever you draw a card, you may have target opponent exile the top card of their library face down.
You may look at and play cards exiled with Thought Siphon, and you may spend blue mana as though it were mana of any color to cast them.

Return two instant and/or sorcery cards at random from your graveyard to your hand. Exile Thoughts Reborn.

Flash
When this creature enters, you may return target instant or sorcery card in a graveyard or nonland permanent to its owner's hand.
Whenever this creature attacks, you may cast a spell from your hand with mana value less than this creature's power without paying its mana cost.

Wu Xing (Add effects based on the number of colors of mana spent to cast this spell.)
1 | Draw three cards.
5 | Add {W}{U}{B}{R}{G}. You can cast only one more spell this turn.

As an additional cost to cast this spell, sacrifice a land.
Creatures you control get +1/+1 and gain trample until end of turn for each land you control.

Flying
When Thunder Shrike enters, choose up to two target permanents. For each of those permanents, you may tap or untap it.

Choose one —
• Draw three cards, then discard a card.
• The owner of target nonland permanent puts it on the top or bottom of their library.

Once each turn, when a creature you control becomes tapped, you may untap that creature and tap up to one target creature.

Menace, haste
Whenever Tiger of the Drums attacks, choose one —
• Exile target opponent's graveyard.
• You draw a card and lose 1 life.
• Torment each opponent. (They lose 3 life unless they discard a card or sacrifice a nonland permanent.)

Enchant creature
When Til Death enters, exile target creature an opponent controls other than enchanted creature until Til Death leaves the battlefield.
Enchanted creature has defender.

Whenever you cast your first noncreature spell each turn, you may draw a card. If you do, discard a card.

Take an extra turn after this one. Exile Time if it wasn't fused.
Fuse (You may cast one or both halves of this card from your hand.)
