This artifact enters tapped. This artifact doesn't untap during your untap step. As long as this artifact is untapped, all players play with their hands revealed. Clap your hands twice: You may tap or untap this artifact.

Whenever you cast an artifact spell, you may search your graveyard, hand, and/or library for a card with the same name as that spell and put it onto the battlefield. If you search your library this way, shuffle.

{0}: This creature gets -1/-1 and gains your choice of banding, flying, first strike, or trample until end of turn. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)

Trample {3}: This creature gains banding until end of turn. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.) {3}: Attacking creatures banded with this creature gain trample until end of turn.

+1: Reveal the top two cards of your library. An opponent chooses one of them.

Read ahead (Choose a chapter and start with that many lore counters. Add one after your draw step. Skipped chapters don't trigger. Sacrifice after III.) I — Scry 4, then you may reveal the top card of your library. If a planeswalker card is revealed this way, put it into your hand. II — You may put a planeswalker card with mana value 6 or less from your hand onto the battlefield. III — You may activate the loyalty abilities of planeswalkers you control twice this turn rather than only once.

{T}, Sacrifice this artifact: Look at a card at random in target player's hand. You draw a card at the beginning of the next turn's upkeep.

Echo {6} (At the beginning of your upkeep, if this came under your control since the beginning of your last upkeep, sacrifice it unless you pay its echo cost.) {T}: Draw a card.

Whenever an artifact you control is put into a graveyard from the battlefield, if it wasn't sacrificed, you may pay {3}. If you do, draw a card.

{3}, {T}: Draw a card. Then discard a card unless you exile a historic card from your graveyard. (Artifacts, legendaries, and Sagas are historic.)

{T}: Add {C}. {4}, {T}: Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

{T}: Add {C}. {7}, {T}: Create a 2/2 colorless Assembly-Worker artifact creature token.

{T}: Add {C}. {T}: Add {∞}. Activate only once and only if you control an Urza's Mine, an Urza's Power-Plant, and an Urza's Tower. {7}, {T}: Head to AskUrza.com and click Urza's Fun House.

{T}: Add {C}. If you control an Urza's Power-Plant and an Urza's Tower, add {C}{C} instead.

{T}: Add {C}. If you control an Urza's Mine and an Urza's Tower, add {C}{C} instead.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.) I — This Saga gains "{T}: Add {C}." II — This Saga gains "{2}, {T}: Create a 0/0 colorless Construct artifact creature token with 'This token gets +1/+1 for each artifact you control.'" III — Search your library for an artifact card with mana cost {0} or {1}, put it onto the battlefield, then shuffle.

{T}: Add {C}. If you control an Urza's Mine and an Urza's Power-Plant, add {C}{C}{C} instead.

Flash Flying You may cast colorless spells and artifact spells as though they had flash. Whenever you cast a spell, if the amount of mana spent to cast that spell is greater than Liberator's power, put a +1/+1 counter on Liberator.

Permanents you control have "Ward—Sacrifice a permanent." Each artifact card in your graveyard has unearth {1}{B}{R}. ({1}{B}{R}: Return the card from your graveyard to the battlefield. It gains haste. Exile it at the beginning of the next end step or if it would leave the battlefield. Unearth only as a sorcery.)

Karn's power and toughness are each equal to the greatest mana value among artifacts you control. At the beginning of your upkeep, add {C} for each artifact you control. This mana can't be spent to cast nonartifact spells. Until end of turn, you don't lose this mana as steps and phases end.

When this creature dies, create a tapped Powerstone token. (It's an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.")

{T}: Add {C} for each artifact you control named Powerstone Shard.

Multicolored spells cost {2} less to cast.

As this artifact enters, choose a creature type. Creature spells of the chosen type cost {2} less to cast.

When Urza enters, create a 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control." Tap an untapped artifact you control: Add {U}. {5}: Shuffle your library, then exile the top card. Until end of turn, you may play that card without paying its mana cost.

As an additional cost to cast this spell, sacrifice an artifact or creature. Destroy target creature or planeswalker.

Kicker {8}{R} (You may pay an additional {8}{R} as you cast this spell.) This spell can't be countered. Urza's Rage deals 3 damage to any target. If this spell was kicked, instead it deals 10 damage to that permanent or player and the damage can't be prevented.

Choose one — • Counter target spell. • Tap up to two target creatures.

When Urza's Sylex is put into exile from the battlefield, you may pay {2}. If you do, search your library for a planeswalker card, reveal it, put it into your hand, then shuffle.

At the beginning of combat on your turn, create a token that's a copy of target noncreature artifact you control, except its name is Mishra's Warform and it's a 4/4 Construct artifact creature in addition to its other types. It gains haste until end of turn. Sacrifice it at the beginning of the next end step.

Choose two — • Creatures you don't control get -2/-0 until end of turn. • Create a tapped Powerstone token. • Create a tapped 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control." • Scry 1, then draw a card.

Whenever Mishra enters or attacks, choose three — • Target opponent discards two cards. • Mishra deals 3 damage to any target. • Destroy target artifact or planeswalker. • Creatures you control gain menace and trample until end of turn. • Creatures you don't control get -1/-1 until end of turn. • Create two tapped Powerstone tokens.
