Each player gains X life, draws X cards, returns X creatures from their graveyard to the battlefield, then returns X lands from their graveyard to the battlefield.

Choose one —
• Destroy all nonland permanent cards originally printed in the Mirrodin, Darksteel, Fifth Dawn, and Scars of Mirrodin expansions.
• Destroy all nonland permanent cards originally printed in the Mirrodin Besieged, New Phyrexia, and Phyrexia: All Will Be One expansions.

Any time a player would pay a mana cost for anything, it costs {1} more mana to activate. (This includes casting spells, activating abilities, turning face-down creatures face up, paying for Ghostly Prison, the weird ability on Quenchable Fire, etc.)

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

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.

Prowess, deathtouch

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 "Equiped creature gets +4/+4 and gains lifelink."

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.

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 the 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.

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.

Science — Whenever you cast an instant or sorcery spell, this creature deals 2 damage to each opponent.

Whenever The Sprinkler of Stardust attacks, look at the top six cards of your library. You may put an instant or sorcery cards from among them onto the battlefield tapped and attacking. It becomes a 2/2 creature with "Whenever this deals combat damage to an opponent, cast a copy of this card." (The 2/2 creature stays on the battlefield.) Put the rest of the cards on the bottom of your library in a random order.

{1}, {T}: Look at the top three cards of your library. Choose one of them that isn't a playtest card and say its name, then choose a category among power, toughness, or mana value. An opponent guesses in that category about that card then reveals the card. If they guessed incorrectly, put the card into your hand. Then, put each card not put into your hand this way on the bottom of your library in any order.
