Tithe (As you cast this spell, you may tap three artifacts and/or creatures you control.)
Create two 1/1 red Cleric creature tokens with haste. If this spell's tithe was paid, create four of those tokens instead.

Ward—Pay 2 life. (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2 life.)
You may cast sorcery spells as though they had flash.
Whenever you cast a sorcery spell, Daiju, Lightning-Draw gets +2/+0 and gains first strike until end of turn.

Whenever a player casts a spell, that player exiles the top card of each library face down.
Each player may look at and play cards they exiled with Mystic of Many Winds.

At the beginning of your upkeep, choose a creature. Its controller may sacrifice it. If that player doesn't, you gain life equal to its power.

When Graygulch Turncoat enters, you may post a bounty on target creature. If you do, each opponent loses life equal to the number of bounty counters on creatures. (Put a bounty counter on that creature. It has “When this creature dies, each opponent draws a card” as long as it has a bounty counter on it.)

[+1]: Create a white enchantment token named Intangible Virtue. It has “Creature tokens you control get +1/+1 and have vigilance.”
[–3]: Create a 4/4 white Angel creature token with flying. You gain life equal to the number of tokens you control.
[–5]: Exile all other nonland, nontoken permanents.

Escalate {1}{W} (Pay this cost for each mode chosen beyond the first.)
Choose one or both —
• Return up to two target creature cards from your graveyard to your hand.
• Abound, abound. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)

When Chigau, the Red Market enters, draw a card, then choose a creature card name.
Once each turn, you may cast a creature spell with the chosen name from your graveyard.

Enchant creature or planeswalker
Enchanted permanent can't attack, block, or transform, and its activated abilities can't be activated.

Artifact and enchantment spells you cast cost {1} less to cast.
Whenever Risti Salvager attacks, rediscover an artifact or enchantment card. (Look at the top card of your library. You may reveal it and put it into your hand if it's an artifact or enchantment card. Otherwise, put it back or into your graveyard.)

Vigilance
When Coralight Sentinel enters, create a white Aura enchantment token named Crab's Resolve attached to target creature. The token has enchant creature and “Enchanted creature gets +0/+2.”

Gain control of target creature with power less than or equal to the number of different creature types among creatures you control.

Enchant land
Enchanted land has “{T}: Each opponent loses 2 life.”

Destroy target artifact or enchantment. Surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

You may return a land you control to its owner's hand rather than pay this spell's mana cost.
Lumenbay Flyer Line enters tapped.
{T}: Add {W}.

Menace
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.)

Destroy each creature with power 3 or greater.

Flying
When Krothuss, Abyssal Terror dies, return all creatures to their owners' hands except for Krakens, Leviathans, Octopuses, and Serpents.
Foreshadow {6}{U}{U} (You may cast this spell for its foreshadow cost. If you do, also trigger its “dies” abilities when it enters.)

Destroy target creature or planeswalker. Create a tapped colorless land token named Fading Rift with “{T}, Sacrifice this land: Add one mana of any color.”

{T}: Add one mana of any color.
{3}, {T}, Sacrifice Coveted Heirloom: Draw a card.
Tap three untapped artifacts you control: Return Coveted Heirloom from your graveyard to the battlefield.

Ceanne, Shield of Caerdyne enters with your choice of a +1/+1, first strike, lifelink, or vigilance counter.
Counters remain on Ceanne as it moves to any zone other than a player's hand or library.
{3}{G/W}: For each kind of counter on Ceanne, put a counter of that kind on another target creature you control. Activate only once each turn and only as a sorcery.

Cloudcover Heights enters tapped unless you control a Forest.
{T}: Add {R} or {W}.

Flying
Menagerie — When Northrime Messenger enters, if there are five or more creature types among creatures you control, you may search your library for a Quest card, reveal it, put it into your hand, then shuffle.

Whenever a land you control enters, you may pay {2}{G}. If you do, put a +1/+1 counter on Atdrik Ravager.

As an additional cost to cast this spell, sacrifice an artifact or creature.
