When The Bus Runner enters, create a 4/4 Desert Vehicle artifact land token with crew 2. Put eight hour counters on it. It has ": Add " and "Whenever this token or a Gamer you control becomes tapped, remove an hour counter from this token. Then if it has no hour counters on it, each opponent loses 1 life, you gain 1 life, and put eight hour counters on this token."
Ready to run (You can have two commanders if both have ready to run.)

Trample
The Judge of Height gets +1/+0 for each creature on the battlefield that it's taller than. (A creature's height is equal to its toughness plus its mana value.)

At the beginning of your upkeep, choose one that hasn't been chosen —
• Wake Up! — Return target creature card from a graveyard to its owner's hand.
• VIP Line Access — Search your library for a card, then shuffle and put that card on top.
• Life of the Party — Whenever a spell is cast this turn, you gain 2 life.
• Breakfast at Dawn — Create two Food tokens. Sacrifice this enchantment.

During deck construction, name a Nephilim card originally printed in Guildpact. Awoken Nephilim has that card's color identity and is a copy of that card in all zones except it's also Legendary.

Ew-minance — When The Gunky Runner enters and at the beginning of the first upkeep in a game where it's your commander, shuffle three Gunk cards into each opponent's library. (Gunk is a colorless sorcery card with no mana cost and cycling .)
Whenever an opponent loses life, they shuffle that many Gunk cards into their library.
Ready to run (You can have two commanders if both have ready to run.)

Treat your effects that scale off of "players" or "opponents" as though there were one more. (For example, with myriad you'd make an additional token that's just attacking nobody, and with Braids, Arisen Nightmare, you'd draw an additional card.)

Trample
When you cast this spell, choose a playtest card you own from outside the game. Exile it. You may cast that card as long as it remains exiled. Mana of any type can be spent to cast that spell. (In a sealed event, outside the game is your sideboard.)

: Add one mana of any color. You get two poison counters.

The Chaos Keeper enters with a sealed Magic booster pack of your choice under it. (You provide a new pack each time.)
Whenever The Chaos Keeper deals combat damage to a player, reveal its cards and put one of them into your hand. (Don't open the booster pack until the first time this ability reolves.)

If it's neither day nor night, it becomes day as The Weekly Princess enters. (It becomes night next turn if a player casts no spells on their turn, and day if a player casts 2+ spells on their turn.)
Whenever night becomes day, put a +1/+1 counter on The Weekly Princess. Then if she has seven or more +1/+1 counters on her, she deals damage equal to her power to each opponent.
When The Weekly Princess leaves the battlefield, it stops being day or night. (Stop tracking it. Trust us, it's better this way.)

At the beginning of your end step, if your life total is on the lazy caterer's sequence, create a Food token. If it's a Fibonacci number, create a 0/0 green and blue Fractal creature token, then put a +1/+1 counter on each Fractal you control. If it's a square number, put three +1/+1 counters on each creature you control whose power and toughness are equal. (You'll want to look these up.)

Spells you cast that would counter a spell cost less to cast.
Whenever a spell an opponent controls is countered by a spell or ability you control, draw a card. The Countering Runner deals 2 psychic damage to that player. (Psychic damage doesn't cause loss of life, but a player who's been dealt 20 psychic damage loses the game.)
Ready to run (You can have two commanders if both have ready to run.)

, : Choose any number —
• You lose X life.
• You discard X cards.
• You sacrifice X permanents.

Flying
Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)
Whenever one or more +1/+1 counters are put on a creature you control, exile the top card of your library. Until end of turn, you may play that card.

This creature enters with two cage counters on it.
This creature can't attack or block as long as it has a cage counter on it.
At the beginning of your upkeep, remove a cage counter from this creature. When the last cage counter is removed this way, destroy target creature an opponent controls.

You may spend any type of mana to cast cards that didn't start in your deck.
Whenever The Wheeling Runner deals combat damage to a player, you may discard your hand. If you do, choose four Vintage-legal cards at random. Add those cards to your hand. (The "Random Card" feature on a search site may help.)
Ready to run (You can have two commanders if both have ready to run.)

Islandwalk, swampwalk (This creature can't be blocked if defending player controls an Island or a Swamp)
Whenever The Milling Runner deals combat damage to a player, target player mills three cards.
Ready to run (You can have two commanders if both have ready to run.)

(: Add .)
The Belligerent and Useless Island enter the battlefield tapped.
When The Belligerent and Useless Island deal combat damage to a player or battle, draw a card, then discard a card.
Crew 2

While it's October 25th, 2024, whenever you cast your commander, create a token that's a copy of it except it isn't legendary.
While it's October 26th or 27th, 2024, if one or more tokens would be created under your control, instead twice that many tokens are created and each of them enters with a +1/+1 counter on it.
On any other date, both abilities apply. (Because why not?)

You may have The Cosplayzer enter as a copy of any creature on the battlefield, except it has "The first time each turn an ability of this creature is activated or triggered, copy it. You may choose new targets for the copy" and the first letter of its name is Z. (This is both stylish AND makes it a different name for the legend rule!)

At Least It's a Dry Heat deals 1,000,000 damage to target creature. This damage can't be prevented, redirected, cause damage to be dealt to a player (sorry, Stuffy Doll), or be compared to damage dealt by sources on the east coast.

At the beginning of your first main phase, read aloud the name, mana cost, type line, power, and toughness of a card in your hand, except lie about one of them. Each opponent simultaneously guesses which one is incorrect. Then reveal the card. Each opponent who guessed incorrectly loses 3 life. You may discard that card and draw a card. (They can't look it up or ask for help as this ability is resolving. Nice try, though.)

At the beginning of combat on your turn, choose one —
• Target creature gets +1/+0 and gains haste until end of turn.
• The Wiley Speedster deals 1 damage to any target.
• Create a Treasure token.

Before the game begins, if The Fifth Alias is your commander or in your deck, secretly make a list of five nonland cards in your deck. (Don't forget to do this!)
As you draw a card on your list, you may reveal it, show it was on the list, and exclaim its name. If you do, cast it without paying its mana cost.

Echo (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.)
When The Keeper of Four Scythes enters, create four Scythe tokens. (They're Equipment with "Equipped creature gets +1/+1" and equip .)
Equipped creatures you control get +1/+1.

At the beginning of each player's upkeep, create a 1/1 blue Serpent creature token named Cobra Coil. When you do, if you control five or more Snakes and/or Serpents, choose one —
• Strike first — Target Snake or Serpent you control fights target creature an opponent controls.
• Strike hard — Put a +1/+1 counter on each Snake and Serpent you control.

If The Zonian Brawler is your commander, your minimum deck size is 60 and your starting life total is 30. (That's right, you're playing Brawl!)
Whenever a fighting or biting creature you control deals lethal damage to a creature, create a Food token and draw a card. (Biting is when a creature deals damage equal to its power to another creature.)

Whenever you cast a spell with a keyword or ability word, if it doesn't share a keyword or ability word with a permanent you control or a card in your graveyard, draw a card. (Keywords and ability words include abilities like flying, flashback, and landfall.)

If Enolc is one of two partner commanders, it's a copy of your other commander except it retains its name. (Including mana cost.)
If Enolc isn't a commander, you may cast it as though it was a copy of any of your commanders.
Partner (You can have two commanders if both have partner.)

Choose two colors. Add a mana of each of the chosen colors.
At the beginning of your next upkeep, pay one mana of each of the chosen colors. If you don't, you lose the game.

You gain 3 life. Draw three cards. Add . This spell deals 3 damage to any target. Target creature gets +3/+3 until end of turn.

If The Covert Blue Mage is your commander, your starting deck can contain any number of cards beyond the maximum deck size. (For example, your deck can be 120 cards.)
When The Covert Blue Mage enters, create a colorless Equipment artifact token named Covert Sunglasses. It has "Equipped creature can't be blocked" and equip .

(Start the game with this conspiracy face up in the command zone.)
Players play with each of their commanders face down and secret until they cast them for the first time. (Be sure to tell your opponent you're using this right at the beginning of the game, so they don't reveal their commanders to you yet!)

The The Magical City, New enters the battlefield tapped.
: Add , , or . When this mana is spent to cast a legendary spell, put a +1/+1 counter on this land.
: The Magical City, New becomes a 1/1 white, blue, and red Human Artist creature until end of turn.
The Magical City, New can be your Commander. (Commander tax still applies.)

All creatures are legendary.
Creatures with a black or silver expansion symbol get +1/+1.
Creatures without a black or silver expansion symbol get +2/+2.

Whenever the The Caffeinated Runner enters or attacks, create a Food token.
Sacrifice a Food: Target creature gains haste until end of turn. Whenever it next becomes tapped this turn, untap it.
Ready to run (You can have two commanders if both have ready to run.)
