Menagerie — Whenever Sigilwing Familiar deals combat damage to a player, if there are five or more creature types among creatures you control, draw a card.

Enchant creature
Enchanted creature gets +1/+1 and has hexproof.

Mill three cards, then counter target spell unless its controller pays {X}, where X is the greatest mana value among cards milled this way.

Target opponent exiles cards from the top of their library until X land cards are exiled, where X is the number of land cards in your graveyard.

Return target creature to its owner's hand. If you controlled that creature, draw a card.

Flash
You may cast cryptic spells as though they had flash. (Artifacts, enchantments, and modal spells are cryptic.)

Flash (You may cast this spell any time you could cast an instant.)
When Silk Crane Adept enters, target creature gains hexproof until end of turn.

{T}: Untap another target nonland permanent. Activate only as a sorcery.

(Add a quest counter as this enters. Sacrifice after 3.)
Whenever you cast your first spell outside your main phase each turn, add a quest counter.
1, 2 — Draw cards equal to the number of quest counters on Siltbottom Expedition, then discard that many cards.
3 — Put up to two target instant or sorcery cards from your graveyard on top of your library in any order, then draw a card.

{2}{U}, {T}: Look at the top card of your library. If it's a Scout card or a card with an Adventure, you may reveal it and draw a card.

Whenever you draw a card, Silverblood Aspirant gets +1/+1 until end of turn.
{1}{R}, Discard a card: Draw a card.

When Silvercrest Historian enters, scry 1, then investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

When Silvercrest Vanguard enters, scry 1, then draw a card.
Whenever you draw your second card each turn, put a +1/+1 counter on Silvercrest Vanguard.

As long as you are glorious, you may look at the top card of your library. (You are glorious as long as you have a glory counter.)

Whenever Skhorvall Patrol deals combat damage to a player, look at the top card of that player's library.

Whenever a player casts an instant or sorcery spell from their hand, you may exile that card as it resolves instead of putting it anywhere else.
