As an additional cost to cast this spell, tap an untapped artifact you control.
Target player discards two cards.

Whenever you conjure a card, if its name isn't noted for Neural Dreams, you may note its name.
Spells you cast with a name noted for Neural Dreams cost one mana of any color less to cast. (If it doesn't have a colored mana symbol in its cost, it costs {1} less.)

Search your library for a creature card with mana value X or less, put it onto the battlefield, then shuffle.
Reconstruct {X}{G}{G}{G} (You may cast this from your graveyard for its reconstruct cost reduced by the mana value of a permanent you sacrifice as you cast it this way. Then exile this.)
You can't sacrifice creatures or lands to pay Never Enough's reconstruct cost.

Whenever New Alores Charmer attacks, you may tap target creature.

Choose one —
• Exile target permanent you control, then return that card to the battlefield under its owner's control.
• Return target permanent you control to its owner's hand. Draw a card.

Whenever a creature you control enters, it gets +2/+1 until end of turn.

If you would choose one or more modes, you may choose an additional mode. (Modal spells and abilities are indicated by • listed modes.)
{1}, {T}: Add one mana of any color.
{6}, {T}: Add {W}{W}{U}{U}{B}{B}{R}{R}{G}{G}.

{U/B}{U/B}: Return Nherix, the Soulcage from your graveyard to the battlefield tapped.
{6}: Return target creature card with mana value 2 or less from your graveyard to the battlefield tapped.

Draw a card. The next noncreature spell you cast this turn costs {2} less to cast.
Showcase {3}{R} (Then if you cast this for its showcase cost, create a 1/1 red Bard creature token that can't block and exile this. Whenever it attacks, you may cast a free copy of this.)

When Night Howlers enters, target opponent reveals three cards from their hand and you choose one of them. Exile that card until Night Howlers leaves the battlefield.

Flying (This creature can't be blocked except by creatures with flying or reach.)
{B}: Night Screecher gains deathtouch until end of turn. (Any amount of damage this deals to a creature is enough to destroy it.)

Target player loses X life and you gain X life, where X is the number of permanents you control with counters on them.

When Night Shepherd enters, return a creature you control to its owner's hand.

Until end of turn, target creature gains deathtouch and “When this creature dies, return it to the battlefield tapped under its owner's control.”

Sacrifice a creature: Look at the top card of target player's library. You may have that player put that card into their graveyard.

Whenever you cast a spell, Nightfire Adept gets +3/+0 until end of turn if that spell has the same name as a card in your graveyard.

Whenever Nightly Herald attacks, it deals damage to the defending player equal to the number of Wolves and Werewolves you control.

Chronicle (As this enters and after your draw step, add a lore counter. Stop after III.)
[Lore I-II] You gain 1 life.
[Lore III] Target creature you control gains first strike until end of turn.

Whenever Nightrail Printer attacks, you may tap target creature.

Reach, deathtouch
When Nightshade Ambusher enters, you may pay {1}{G}. When you do, destroy target creature with flying.

Nightshade Cultivator has deathtouch as long as five or more cards are in your graveyard.

Whenever a creature dies, its controller loses 1 life.

Once each turn, when another creature dies, you may crystallize. (Put a +1/+1 counter on a creature you control or create a Treasure.)
Whenever an artifact you control dies, Nihilistic Shock Trooper deals 1 damage to each opponent.

First strike
Crew 1 (Tap any number of creatures you control with total power 1 or greater: This Vehicle becomes an artifact creature until end of turn.)

Deception {B} ({B}, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)
Lifelink
{1}{B}: Nimunotian Shadow gets +1/+1 until end of turn.
