Artifacts and lands enter tapped.

Rouse 4. (Distribute four +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.)

At the beginning of your upkeep, sacrifice a land, then search your library for up to two land cards, put them onto the battlefield tapped, then shuffle.

[–2]: Target player sacrifices a creature, then loses life equal to the greatest power among creatures they control.
[–5]: Choose a nonland card name. Exile all creatures and planeswalkers with that name, then search target player's graveyard, hand, and library for any number of cards with that name and exile them. That player shuffles.

Archive 5 (As this enters, shuffle the top five cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you draw a card from another one of your libraries, you draw a card from the archived library and you lose 1 life.

At the beginning of your end step, if you don't control a creature, create a 1/1 white Human creature token and attach Seeking Sword to it.
Equip {1}

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.

Choose one —
• Untap each creature you control.

Orchestrate {B} (You may exile this card from your hand anytime you could cast a sorcery for its orchestrate cost. When you next resolve a spell, you may cast this from exile without paying its mana cost.)

If a spell or ability would cause a player to discard one or more cards, that player discards that many cards at random instead.
Whenever a player discards a card, that player loses 2 life.

Cards can't leave graveyards.

Target creature gains trample and haste until end of turn. Harmonize. (Trigger up to one harmony of a permanent you control.)

Draw two cards.
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.”)
