Harmony — Draw a card.
When Enthralling Actor enters, harmonize. (Trigger up to one harmony of one permanent you control.)

You may have Enthusiastic Double enter as a copy of any permanent on the battlefield, except it's 4/4, it's a creature in addition to its other types, and it has haste.

Menace
Whenever Entrail Elemental deals combat damage to a player, you may cast target card from your graveyard this turn. If an instant or sorcery spell cast this way would be put into your graveyard, exile it instead. (You still pay its costs. Timing rules still apply.)

Enchant creature
You control enchanted creature.
Enchanted creature gets +1/+1 and has slipstream. (This creature can't be blocked as long as only creatures with slipstream are attacking.)

Return target card from your graveyard to your hand. Distribute X +1/+1 counters among any number of creatures you control, where X is that card's mana value. Exile Entropic Harvest.

Entropic Inferno deals 5 damage divided as you choose among any number of targets. At the beginning of the next end step, for each permanent dealt damage this way, its owner puts it on the bottom of their library, then reveals cards from the top until they reveal a nonland permanent card. They put that card onto the battlefield, then shuffle.

{T}: Envious Nereid deals 1 damage to target creature and 1 damage to that creature's controller.

Menace, ward {2}
Whenever Envoy of Divine Progress deals combat damage to a player, you may search your library for an enchantment card, reveal it, put it into your hand, then shuffle.

When Envoy of Growth enters, search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Vigilance
When Envoy of Karametra enters, for each kind of counter on target permanent, put another counter of that kind on it or remove one from it.

Indestructible
As long as your devotion to white and blue is less than seven, Ephara isn't a creature.
You may cast creature and enchantment spells as though they had flash.
Whenever another creature or enchantment you control enters, you gain 1 life.

Enchant creature
Enchanted creature has double strike.
Mirage {1}{W} (You may cast this spell as though it had flash for its mirage cost. If you do, sacrifice it at the beginning of the next cleanup step.)

Epic Boss Fight deals 5 damage to target creature or planeswalker.
Menagerie — If there are five or more creature types among creatures you control, Epic Boss Fight deals 3 damage to that permanent's controller.

Create two tokens that are copies of target noncreature artifact or noncreature artifact card in a graveyard.

Choose X. You may choose the same mode more than once.
• Epic of Anku deals 4 damage to each creature.
• You draw three cards and you lose 3 life.

• Counter target spell unless its controller pays {3}.
• Return target nonland permanent to its owner's hand.

Haste
Whenever another creature you control enters or attacks, Epitome of Force gets +1/+0 until end of turn. If this is the third, sixth, or ninth time this ability has triggered this turn, Epitome of Force gains your choice of first strike, menace, or trample until end of turn.

Flying, haste
Whenever Epoch Warden attacks, you may aetherize another target attacking creature you control. (To aetherize, create a token that's a copy of it, then exile that token.)

Flash
Creatures other than Equilibrium Paladin that entered this turn lose all abilities and have base power and toughness 1/1.

Wu Xing (Add effects based on the number of colors of mana spent to cast this spell.)
1 | Each creature deals damage to itself equal to its power.
3 | You gain life equal to the excess damage dealt this way.
5 | Each opponent loses that much life.

When Equinox Sprite enters, return target card from your graveyard to your hand.

You draw X cards and you lose X life, where X is the number of different names among land cards in your graveyard.

Eradicating Flames deals X damage to each creature and each player. If X is 5 or more, Eradicating Flames can't be countered and the damage can't be prevented.

Exile target creature and all other creatures with the same name as that creature. Search its controller's graveyard, hand and library for any number of cards with the same name as that creature and exile them. Then that player shuffles. Exile Erase from Existence.

Vigilance, spirited (When this enters, you may activate one of its activated abilities without paying its costs.)
{T}: Choose artifact or enchantment. Target nonland permanent becomes the chosen type in addition to its other types until end of turn.
Civilized — At the beginning of your end step, if you control an artifact, a creature, and an enchantment, put a +1/+1 counter on target creature you control.
