Improve {1} ({1}: Put a +1/+1 counter on this creature. This costs {1} more to activate for each +1/+1 counter on it. Improve only as a sorcery.)
{T}: Add one mana of any color.
{T}: Add X mana of any one color, where X is the greatest number of counters among creatures you control.

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

Whenever a Role is attached to a creature you control or you cast a spell that targets a creature you control, put a +1/+1 counter on Enthusiastic Admirer.

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.

Whenever another creature dies, upgrade Entitled Griefer. (Give it one of the listed counters it doesn't already have.)
• +1/+1
• Deathtouch
• Lifelink

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.)

Choose one —
• Prevent all damage that would be dealt by creatures this turn.
• Harmonize twice. (Trigger up to one harmony of a permanent you control.)

Haste
{W}, {T}: Tap target creature.

Whenever you attack, you may discard a card. If you do, exile the top two cards of your library. You may play one of them this turn.
Once each turn, when a card leaves your graveyard, you may add {C}{R}.

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.

Choose one —
• Destroy target artifact.
• Destroy target enchantment.
• Destroy target creature with flying.
• Target creature you control fights target creature an opponent controls.

Equipped creature gets +1/+0 and has poisonous 1. (Whenever it deals combat damage to a player, that player gets a poison counter.)
Equip {1}

Flying
Once each turn, when an opponent draws a card while they have more cards in hand than you, you may draw a card.

{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.

{T}: Add {C}.
{4}, {T}, Sacrifice Eon Campfire: Destroy target artifact or nonbasic land.

Encourage ({T}: Another target creature you control gets +1/+1 until end of turn. Encourage only as a sorcery.)
Whenever Eos Beseecher encourages a creature, look at the top card of your library. If it's a creature card with power 2 or less, you may reveal it and put it into your hand.

Flying
When Ephara's Watcher enters, scry 2.

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.

You may have Ephemeral Qilin enter as a copy of a multicolored permanent you control.

Flying, lifelink
