Exile target nonland permanent if its mana value is less than or equal to the greatest number of nonland permanents controlled by a single player.

Reveal the top two cards of your library. Put up to one land card and up to one nonland card from among them into your hand. Put the rest on the bottom in any order.

Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. Then if you control seven or fewer lands, return Evergrowth to your hand.

When Evermind's Watch enters, conjure a card named Data-Point into your hand. (It's a sorcery that costs {2} with “Draw a card.”)
Once each turn, when you activate a loyalty ability, you may create a Function token with its effects. (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell.)

Draw four cards.

Permanents you control are black. The same is true for spells you control and nonland cards you own that aren't on the battlefield.
At the beginning of your upkeep, you may pay {B}. If you do, you draw a card and you lose 1 life.

At the beginning of your end step, exile up to one other target nonland permanent you control, then return it to the battlefield under your control.

As Evil One's Mind Tricks enters choose Lafterii or Evil One.
• Lafterii — Wizards you control have “{3}{U}, {T}: Draw a card.”
• Evil One — Whenever a Zombie you control enters, target player mills two cards.

Draw three cards.

Exile target creature or planeswalker. Its controller conjures a card named Data-Point into their hand. (It's a sorcery that costs {2} with “Draw a card.”)

{T}, Sacrifice Evolving Wilds: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Enchant creature
Enchanted creature gets +2/+2.
Whenever enchanted creature attacks, create a 2/2 white Knight creature token that's tapped and attacking.

{2}, {T}: Reveal the bottom card of your library. You gain life equal to its mana value. You may put it into your graveyard.

Scry 5.

Exile target creature and all other creatures with the same name as that creature. Search all graveyards, hands, and libraries for any number of cards with the same name as that creature and exile them. Then players shuffle their libraries searched this way.

Draw a card.

Destroy target creature with power equal to its toughness.

When Exergetic Chains enters, exile target nonland permanent you don't control and up to one target creature you control until Exergetic Chains leaves the battlefield.

Put target spell on top of its owner's library.
Each player conjures a card named Fatigue and puts it on top of their library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

If a player would draw one or more cards, instead that player draws that many cards plus one and loses 1 life.

{1}: Put a -1/-1 counter on target creature you control. Untap that creature.
