After a player chooses two or more modes while casting a spell, you may pick one of those modes. That mode is no longer chosen. (That player doesn't pick targets or pay costs related to that mode. If a mode is chosen multiple times, only one instance of that mode is lost.)

When Almgrove Performer enters, harmonize. (Trigger up to one harmony of a permanent you control.)
Harmony — You gain 3 life.

When Banishing Initiate enters, you may exile target nonland permanent you don't control until Banishing Initiate leaves the battlefield.
At the beginning of your end step, sacrifice Banishing Initiate if a card exiled with it has mana value 3 or greater.

When Compulsory Studies enters, exile target creature until Compulsory Studies leaves the battlefield. Each player draws a card.

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.)

Double strike
When Fencing Tutor enters, create a 0/1 white Soldier creature token with double strike.

Whenever Illumination Savant attacks, harmonize. (Trigger up to one harmony of a permanent you control.)
Harmony — Put a +1/+1 counter on each artifact creature and enchantment creature you control.

When you cast this spell, copy it for each color of mana spent to cast it beyond the first.
Flying

Whenever you cast a spell, you gain 1 life for each of its colors other than white.

When Recollection Revelation enters, rouse 1. (Put a +1/+1 counter on a permanent you control. If it isn't a creature, tap it and it becomes a 0/0 creature in addition to its other types.)
{1}{W}, Sacrifice Recollection Revelation: Return another target artifact or enchantment card from your graveyard to your hand.

When Sending Stones enters, harmonize twice. (To harmonize, trigger up to one harmony of a permanent you control.)
If you would harmonize, you may trigger a harmony of a permanent card in your graveyard instead.

Choose one —
• Target permanent gains protection from instants and sorceries until end of turn.
• You gain 3 life.
• Draw a card.

Flying
Whenever Skyline Climber attacks, another target creature you control gains flying until end of turn.

Flying
Whenever Wind Savant attacks, harmonize. (Trigger up to one harmony of a permanent you control.)
Harmony — Wind Savant gets +1/+1 until end of turn.

At the beginning of your upkeep, target player mills two cards. If your main library has five or fewer cards in it, that player mills their library instead.

If an opponent would draw one or more cards, that player instead draws that many cards plus one, then exiles a card from their hand.
You may play cards exiled by Curated Citations, and you may spend mana as though it was mana of any type to cast them.

Choose one —
• Counter target creature or planeswalker spell.
• Return target creature or planeswalker to its owner's hand.

Any number of target players mill twice X cards, where X is the number of artifacts and enchantments you control. Then you may cast a nonland card with mana value X or less from a graveyard without paying its mana cost. You can't cast more spells this turn.

Put target spell on top of its owner's library.
Each player conjures a card named Fatigue and puts it on top of their library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

Sacrifice a creature: Harmonize. (Trigger up to one harmony of a permanent you control.)
Harmony — Look at the top two cards of your library. Put any number of them into your graveyard and the rest back on top in any order.

Defender
When Friend of Tides enters, rouse 2. (Distribute two +1/+1 counters among permanents you control. If they aren't creatures, tap them and they become 0/0 creatures in addition to their other types.)

When Humble Archivist enters, you may return target instant or sorcery card from your graveyard to your hand. If you do, conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

Reveal the top two cards of your library. Put one of them into your hand, then target opponent may have you put the other on the bottom of your library. (Otherwise put it back on top.)

[+1]: For each player, exile the top three cards of that player's library, then put one of those cards into that player's hand.
[0]: Choose target card exiled by Rahit. Until your next turn, you may play that card, and you may spend mana as though it was mana of any type to cast it.
[–7]: Target player draws seven cards.
