At the beginning of each player's upkeep, put a darkness counter on target nonland permanent they control. That permanent is black for as long as it has a darkness counter on it. Then if there are five or more nonland permanents on the battlefield and they are all black, you may exile Tahiel, Elder Kalku and gain control of target creature or planeswalker.

At the beginning of each upkeep, choose one that hasn't been chosen —
• Exile target tapped nonland permanent.
• Draw two cards, then discard a card.
• Return up to two target permanent cards from your graveyard to your hand.
• Exile Take the City, then return it to the battlefield under your control.

Noncreature, nonland permanents you control have hexproof.
Tap five untapped noncreature, nonland permanents you control: Scry 3, then draw three cards.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever a source you control deals noncombat damage to a player, draw a card from the archived library.

Players skip their untap steps during extra turns.

When Tempting Gate enters, draw a card, then choose a card name.
At the beginning of your end step, you may exile any number of target creatures you control with the chosen name, then return them to the battlefield under your control.

Flash
When Tenvilu, Earthen Warden enters, other creatures you control get +2/+2 and gain hexproof and indestructible until end of turn.

Whenever you draw a card except for the first one you draw in each of your draw steps, each opponent loses 1 life.

[+1]: Return target nonland permanent to its owner's hand. That player loses 2 life.
[0]: Create a 1/1 blue Bird creature token with flying for each loyalty counter on The Flock.
[–6]: You get an emblem with “If a permanent you don't control would leave the battlefield, you may instead exile it, then return that card to the battlefield under your control. It's a 1/1 blue Bird creature with flying.”

Destroy all nonland permanents. Draw a card for each card type among cards in graveyards.
