When Reverence Seeker dies, you may return another target Knight card from your graveyard to your hand.

Shuffle your graveyard into your library, then draw two cards.

This spell can't be countered.
Exile your library, then shuffle Revisionary Studies, your graveyard, and your hand into your library. Draw five cards.

When Rework the Canvas enters, purge. (Exile two cards that share a type from graveyards. If you do, draw a card.)
Whenever one or more cards are put into exile from anywhere, you gain 2 life and scry 1.

Whenever you cast an instant or sorcery spell, put a loyalty counter on Reytali of Endless Muses.
[0]: Add X mana in any combination of colors, where X is the number of spells you've cast this turn.
[–3]: Create two 3/1 red Sand creature tokens with haste.

Each instant and sorcery card in your hand has orchestrate. Its orchestrate cost is equal to its mana cost reduced by {2}. (You may exile those cards from your hand anytime you could cast a sorcery for their orchestrate cost. When you next resolve a spell, you may cast it from exile without paying its mana cost.)
When you cast your third spell this turn, exile Reytali, then return her to the battlefield transformed.

{T}, Sacrifice Rickety Guildhall: Search your library for a Forest or Island card and put it onto the battlefield tapped, then shuffle.

Enchant creature
Enchanted creature has “At the beginning of each player's end step, that player chooses another creature they control. That creature fights enchanted creature.”

Scry 1, then you draw a card and you lose 1 life.

First strike
Engage (This creature must be blocked each combat if able.)

Vanishing 3 (This permanent enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
When the last time counter is removed from Rising Riots, destroy target land.

Return target creature or land card from your graveyard to your hand.

Look at the top five cards of your library. You may reveal a land or enchantment card from among them and put it into your hand. Then put the rest on the bottom of your library in any order.

Whenever Rolling Homestead becomes a creature, nourish 1. (To nourish 1, either put a +1/+1 counter on this creature or create a 1/1 white Citizen creature token.)
Crew 2 (Tap any number of creatures you control with total power 2 or greater: This Vehicle becomes an artifact creature until end of turn.)

Artifacts and lands enter tapped.

{1}{B}, Exile a creature or land card from your graveyard: Return Rotwood Whisper from your graveyard to the battlefield tapped.
