Whenever Tremor Titan enters the battlefield or attacks, each player sacrifices a permanent. Then you draw a card for each opponent who sacrificed a land this way.

Flying, menace, haste
Twisted Archangel has indestructible as long as an opponent has four or more cards in hand.

Cast this spell only if you have 10 or less life.
Flying, trample

Put two +1/+1 counters on up to one target creature.
Coalesce {6}{G}{G} (You may cast this from your graveyard for its coalesce cost. If you do, put it onto the battlefield as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

Flying, trample
When Whisper in the Rift enters the battlefield, target player mills half their library, rounded down.
When Whisper in the Rift dies, you may cast up to two instant, sorcery, and/or creature cards from among opponent's graveyards without paying their mana cost.

Destroy all non-Horror creatures.
Coalesce {8}{W}{W} (You may cast this from your graveyard for its coalesce cost. If you do, put it onto the battlefield as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

This spell costs {1} less to cast for each creature that died this turn.
At the beginning of your upkeep, put target creature card from a graveyard onto the battlefield under your control.
{1}, Sacrifice another creature: Zarad gains indestructible until end of turn.

When 11-A Lionheart enters the battlefield, it deals 2 damage to each nonartifact creature.

Each player mills four cards.
Coalesce {5}{U}{U} (You may cast this from your graveyard for its coalesce cost. If you do, put it onto the battlefield as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
When A Vision Too Vast enters the battlefield, you may cast target noncreature, nonland card with mana value 4 or less from a graveyard without paying its mana cost.

Vigilance, reach
As a noncreature spell resolves, exile it instead of putting it anywhere else.

At the beginning of your end step, you lose 3 life unless you sacrifice a creature.

Trample
Each creature you control with a counter on it has trample.

If another multicolored card would be put into your graveyard from anywhere other than your hand or library, if no cards exiled with An'yama, Elder Guardian are exactly that card's colors, you may instead exile that card and put a +1/+1 counter on An'yama.
As long as An'yama has four or more counters on them, they have protection from everything.

Ward {3}

Protection from instants and from sorceries
At the beginning of your upkeep, sacrifice another creature. For each creature sacrificed this way, put a +1/+1 counter on Andazir, the Crownless.
At the beginning of your end step, if you control four or fewer creatures, transform Andazir.

You may put a creature or Revelation card from your hand onto the battlefield. Exile that permanent if it would leave the battlefield. If it's a Revelation, it enters the battlefield as a Horror creature.

Vigilance, trample
Whenever another Horror enters the battlefield under your control, choose one —

When Awoken Animus enters the battlefield, create two 1/1 colorless Shapeshifter creature tokens with changeling. (They're every creature type.)

Backstabbing Courtiers can't attack unless you foretold a card or cast a foretold spell this turn.

Indestructible
