Creatures you control get +X/+0, where X is the greatest number of consecutive nonland, nontoken permanents in a mana curve you control. (For example, if you have permanents with mana value 3, 4, and 5, creatures you control get+3/+0. If you're missing 4, they only get +1/+0.)

When The Keeper of Favorite Cards enters the battlefield or attacks, name a nonland card and write it on your favorites list for this game. (You can have limitless favorites.)
Your favorite creatures get +1/+0.
Whenever you cast a favorite noncreature spell, create a 1/1 white Soldier creature token.

First strike, vigilance
Heroic — Whenever you cast a spell that targets Anax and Cymede & Kynaios and Tiro, draw a card. Each player may put a land card from their hand onto the battlefield, then each opponent who didn't draws a card.

When you cast The Water Maro, create a token that's a copy of it, except the copy isn't legendary.
The Water Maro's power and toughness are each equal to the number of permanents you control that are tokens and/or have the word "Maro" in the name.

Rulebreaker — If Valko Indorian, Researcher is your Commander, you may include all artifacts and enchantments in your deck regardless of color identity.
Artifacts and enchantments you own everywhere become both types. (This applies to your library, hand, battlefield, and so on.)
Whenever you cast an artifact or enchantment spell, put a +1/+1 counter on Valko Indorian.

Onionfect (This creature deals damage in the form of giving you Food tokens.)
At the beginning of your end step, put X +1/+1 counters on target creature you control, where X is the number of Foods you've sacrificed this turn.
Crew 1
The Vegetable Car can be your commander.

Prowess, deathtouch
When you cast Kallist Rhoka, you may choose a creature or planeswalker on the battlefield. Kallist Rhoka becomes a copy of that creature or planeswalker, and that creature or planeswalker becomes a copy of Kallist Rhoka.

You can't cast Keeper of the Yellow Hat during your first seven turns of the game. (Keep track if you're playing with this!)
When The Keeper of the Yellow Hat enters the battlefield, create a legendary artifact equipment token named Yellow Hat with equip {2} and "Equipped creature gets +4/+4 and gains lifelink."

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.)

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.)

Vehicles in your graveyard have jump-start. (You may cast a Vehicle card from your graveyard by discarding a card in addition to paying its other costs. You would exile it, except...)
Spells you cast with jump-start aren't exiled.

Before this game begins, if this is your commander, secretly write down the name of five nonartifact creature cards in your deck to be invaders. Reveal them after the game.
At the beginning of your upkeep, target opponent may guess if a creature you control is an invader. If they guess right, exile that creature. If they guess wrong, they lose 3 life. Then you may reveal the name of an invader you control. If you do, put two +1/+1 counters on it. It becomes a Robot artifact creature.

Double strike, vigilance, haste
Whenever The Herald of Numot deals combat damage to a player, create a Numot, the Devastator token card and shuffle it into your library.
Numot, the Devastators you control have vigilance and haste, and the "legend rule" doesn't apply to them.

You can sacrifice creatures and artifacts interchangeably. (If an effect asks you to sacrifice one of them, you can sacrifice either.)
{1}, {T}, Sacrifice another artifact or creature: Put a rebuilding counter on Slobad.
{T}, Remove 3 Rebuilding Counters from Slobad: Create a token that's a copy of Bosh, Iron Golem.

Grumpy Co-play — When The Egotistical Velociraptor enters the battlefield, if you cast it, you may choose another Magic player not currently in a game of Magic and ask them to take over your game until the end of your next turn. If they agree, shuffle your hand into your library, draw four cards and gain 4 life. (You can't give them advice, but witty banter is encouraged.)

When The Keeper of Kaldra enters the battlefield, if it's the first time this ability has resolved this game, add Helm of Kaldra, Shield of Kaldra, and Sword of Kaldra as your companions. (You can pay {3} to put one into your hand from outside the game, once each. Use tokens to represent those cards.)
Creatures you control named Kaldra have hexproof.

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.)

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.)

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.)

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.

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.)

Start your engines!
Gomif's power is equal to your speed.
Your speed can increase beyond 4. (You're still at max speed at 4 or greater.)
At the beginning of your end step, if an opponent lost life this turn, you may draw cards equal to your speed. If you do, discard two cards.

If you would guess a card, instead just choose the outcome you want.
At the beginning of each opponent's upkeep, look at the top card of their library. Tell them the name of that card. They tell you its mana cost, type line, power, and toughness. Then reveal that card. If they got anything wrong, draw a card.

{1}, {T}: Choose a tournament-legal Mox you don't control at random. Create a token that's a copy of it. Then if you control all ten, create a Mox Lotus token. (The ten are Amber, Chrome, Diamond, Emerald, Jet, Opal, Pearl, Ruby, Sapphire, and Tantalite. Perhaps roll a d10?)
{W}{U}{B}{R}{G}: Untap The Mox Painter.

Eminence — As long as Efteekay is in the command zone or on the battlefield, other Kavu spells you cast cost {1} less to cast.
Whenever Efteekay or another Kavu you control enters, it deals damage equal to its power to target creature.
