Flying
Whenever Everember Phoenix deals combat damage to a player or planeswalker, you may put target exiled card you own or card in your graveyard that shares a name with it into your hand.
Revive {1}{R}{R} ({1}{R}{R}, Exile this card from your graveyard: Create a token that's a copy of this card, except it has no mana cost. Activate this ability only any time you could cast a sorcery.)

Trample
Evergrowing Hydra enters with X +1/+1 counters on it.
Whenever another creature you control dies, you may pay {X}, where X is less than or equal to that creature's power. If you do, put X +1/+1 counters on Evergrowing Hydra.

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.)

When Evershedder dies, you may put it on the bottom of its owner's library.
Morph {2}{B} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up any time for its morph cost.)

Flying, vigilance

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.

When Everything Is Going Great enters, create a 4/4 Elemental creature token that's all colors.
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.

Untap all creatures you control. They get +0/+2 until end of turn.

When Evigian Crusher enters, untap all creatures you control.
Orchestrate {1}{W}{W} (You may exile this card from your hand anytime you could cast a sorcery for its orchestrate cost. When you next resolve a spell, you may cast this from exile without paying its mana cost.)

Vigilance
{W}{U}: Each creature you control assigns combat damage equal to its toughness rather than its power this turn.

This spell costs {1} less to cast for each tapped creature your opponents control.
{5}{U}: Evigian Titan can't be blocked this turn.

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.

{T}: Create an X/X green Elemental creature token, where X is Evoker of the Ancient Form's power.

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.”)

When Evolving Elemental enters, scry 3, then reveal the top card of your library. Put a number of +1/+1 counters on Evolving Elemental equal to that card's mana value.

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

Sacrifice a creature: You lose life equal to the sacrificed creature's power and draw cards equal to its toughness.

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

First strike
When Excavator of the Beyond enters, rediscover an artifact card. (Look at the top card of your library. You may reveal it and put it into your hand if it's an artifact card. Otherwise, put it back or into your graveyard.)

Scry 5.

{T}: Draw a card, then discard a card.
Whenever you cast an instant or sorcery spell, untap Exchange Scholar.

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.
