Flying, trample
When Whisper in the Rift enters, target player mills half their library, rounded down.
When Whisper in the Rift dies, you may cast up to two instant, sorcery, and/or creature cards from among opponent's graveyards without paying their mana cost.

Choose one or both —
• Each player sacrifices an artifact.
• Each player sacrifices an enchantment.

Unearthed Legion's power and toughness are each equal to the number of cards in your graveyard.
At the beginning of your upkeep, mill a card.

Harmony — Creatures you control gain double strike until end of turn.
When Twirling Duet enters, harmonize. (Trigger up to one harmony of one permanent you control.)

Prowess
Wither (This deals damage to creatures in the form of -1/-1 counters.)

Exile a nonland card from your graveyard: For each colored mana symbol in that card's mana cost, add one mana of that color. Activate only once each turn. (For example, if the card's mana cost is {3}{G}{G}{W}, you add {G}{G}{W}.)

Flying, haste

Trample
{1}{G}{W}, Discard Enduring Force: Search your library for up to two basic land cards, reveal them, put them into your hand, then shuffle.
{G}{W}: Return Enduring Force from your graveyard to your hand. Activate only as a sorcery.

Deception {U} ({U}, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)
Whenever a Pirate or Rogue you control deals combat damage to a player, rediscover a Pirate or Rogue card. (Look at the top card of your library. You may reveal it and put it into your hand if it's a Pirate or Rogue. Otherwise, put it back or into your graveyard.)

Whenever you cast a Dwarf or Elf spell, exile the top card of your library. You may play it this turn.
Whenever you cast your third spell each turn, Celitiene deals 2 damage to any target. If you control a Dwarf, Celitiene gets +2/+2 and gains trample until end of turn. If you control another Elf, you gain 2 life.

({T}: Add {B}.)
As Midnight Gate enters, you may pay 1 life. If you don't, Midnight Gate enters tapped.
Basic lands you control have “{T}: Add {B}.”

As an additional cost to cast this spell, sacrifice X lands and/or creatures.
This spell can't be countered.
Create X tapped colorless enchantment land tokens named Paradise with hexproof and “{T}: Add one mana of any color.”

Draw two cards. Then discard a card unless you attacked this turn.

Exile any number of target creatures you control. At the beginning of the next end step, return to the battlefield tapped each creature card exiled this way and each creature card put into your graveyard from the battlefield this turn.

Lifelink
When Herald of Royalty enters, creatures you control get +1/+1 and gain vigilance until end of turn.

You may play lands from graveyards.
{9}{G}{G}: Put nine +1/+1 counters on Jirada, Elder of Caulte.

At the beginning of your upkeep, reveal the top card of your library. If it has the same name as a card in your graveyard, put the revealed card into your hand. Otherwise, put it into your graveyard.

Whenever Guided Occultist attacks, upgrade it. (Give it one of the listed counters it doesn't already have.)
• +1/+1
• Menace

Flash
You may cast Angel and Nephilim spells as though they had flash.

When Skeletal Shredwing enters, target creature can't block this turn.
