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.

Whenever a card is exiled because it was warped, put three time counters on it. It gains suspend.

When Pirk enters, create a legendary Spacecraft token. It's a 2/2 with flying at 6+. Name it.
Whenever you fully station a Spacecraft, draw a card. (A Spacecraft is fully stationed when you unlock its highest station number.)

Whenever The Policy Maker enters or attacks, ask a player outside the game to propose a new rule. If each player in the game agrees to the rule, apply it for the rest of the game. If an opponent doesn't agree to the rule, put a +1/+1 counter on The Policy Maker.

When The Cookout Creator enters, create a Food token.
At the beginning of your upkeep, create a 1/1 colorless Human creature token for each Food you control.
Tapped four untapped Humans you control: You draw a card and create a Treasure token.

Establishing Shot — At the beginning of your first upkeep, if The Good Gamers is in the command zone, it deals 2 damage to each opponent.
When The Good Gamers enters, create X tokens that are copies of it. Give this creature and the tokens unique names.
All damage dealt by this creature to an opponent counts as commander damage for your commander (including noncombat damage and even if this isn't your commander).

Other Wizards you control get +1/+1.
Whenever the Wizardly Barge attacks, create a token that's a copy of a random tournament-legal Wizard creature. (I'd suggest looking them all up online and choosing one at random.)
Crew 1

Whenever you cast a creature spell, you may draw on it. If you drew wings, it enters with a flying counter on it. If you drew boots, it enters with a haste counter on it. If you drew fangs, it enters with a deathtouch counter on it. If you drew something else, it enters with a +1/+1 counter on it. (Previous drawings don't count. For example, if you gave it boots last game, give it more boots. Bigger boots. Boots in unexpected places.)

{2}, {Q}: The Ice Dancer gains flying until end of turn. ({Q} is the untap symbol.)
Whenever The Ice Dancer deals combat damage to a player, create a Gold token. Then you draw X cards and gain X life, where X is the number of artifact tokens you control. The Ice Dancer deals X damage to each opponent. (A Gold token is an artifact with "Sacrifice this token: Add one mana of any color.")

Creatures that haven't shared their feelings can't attack or block.
All creatures have "{2}: Put a +1/+1 counter on this creature. You gain 1 life. This creature shares its feelings. Activate only as a sorcery. (Creatures can continue to share their feelings.)"
{T}: Add two mana of any one color.

During your turn, The River Warlock has flying, lifelink, and indestructible.
Whenever The River Warlock attacks, you and defending player each draw a card, then discard a card. If you discarded a card with equal or greater mana value than the card that player discarded, look at their hand. Exile a nonland card from it until The River Warlock leaves the battlefield.

When Forestfolk enters the battlefield, you may search your library for a basic land card, put it onto the battlefield tapped, then shuffle.
When Forestfolk leaves the battlefield, draw a card.

Rulebreaker — If Hadran, Naya Sunseeder is your Commander, you may include creature cards of power 4 or greater of any color in your deck regardless of color identity.
{T}: Add one mana of any color.
Whenever a creature with power 4 or greater enters the battlefield under your control, draw a card.

First strike, reach
At the beginning of combat on your turn, mill four cards. You may choose a creature card from among them and cast it. When you do, it gains haste, becomes a Zombie in addition to its other types, and enters the battlefield with X +1/+1 counters on it, where X is Halana and Alena and Gisa and Geralf's power.

Any number of Role enchantments can be attached to Maeve, Wearer of Many Hats. (You don't sacrifice the old one when you attach a new one.)
Maeve gets +1/+1 for each Role attached to it.
Whenever you attach a Role to Maeve, draw a card.

When Princess Snowfall enters the battlefield and at the beginning of your upkeep, create a token that's a copy of Seven Dwarves. When you do, each Dwarf you control deals 1 damage to any target.

Double strike
{U}{R}: Copy target instant or sorcery spell you control. Activate this ability only once.
{G}{U}: Copy target creature spell you control. Activate this ability only once. (Copies of permanent spells enter the battlefield as tokens.)

Whenever Shahrazad and Sindbad deals combat damage to an opponent, if there haven't been any subgames this match, players play a Magic subgame using their libraries as their decks. Each player who doesn't win the subgame loses half their life, rounded up.
{T}: Draw a card and reveal it. If it isn't a land card, discard it.

Whenever this creature attacks, look at the top six cards of your library. You may put a Cat creature card from among them onto the battlefield tapped and attacking. Put the rest of the cards on the bottom of your library in a random order. If you don't put a card onto the battlefield this way, create a token that's a tapped and attacking copy of Lurrus of the Dream-Den.

{3}{U}, {T}, Sacrifice another creature: Search your library for up to four cards that don't share a mana value, power, toughness, or card type with each other. Target opponent chooses two of those cards. Put the chosen cards into your graveyard and the rest into your hand. Then shuffle.
