Tribute 4 (As this creature enters, an opponent of your choice may put four +1/+1 counters on it.)
When Slaughter enters, if tribute was paid, destroy all other creatures. Otherwise, destroy all creatures you don't control.

Deathtouch, menace
Slayer of the Famed must be blocked each combat if able.

Search target opponent's library for a card with mana value 3 or less and exile it with a smoke counter on it. Then that player shuffles. You may play that card for as long as it remains exiled, and you may spend mana as if it were any color to cast it.

Destroy target creature unless its controller pays {3}.

Flying, trample, haste
{W}{U}{B}{R}{G}: Create a token that's a copy of another target creature except it's all colors and has haste.
{W}{U}{B}{R}{G}, Exile Soul of Iscathia from your graveyard: Create a token that's a copy of target creature except it's all colors and has haste.

Protection from colored spells
{5}{C}{C}: Exile target colored permanent.
{5}{C}{C}, Exile Soul of Muetar from your graveyard: Exile target colored permanent.

Tap two untapped creatures you control: Harmonize. (Trigger up to one harmony of one permanent you control.)
Harmony — Choose one —
• Soul of New Alores becomes a creature in addition to its other types until end of turn.
• Put two +1/+1 counters on target permanent.

Prowess, trample
During your turn, each instant and sorcery card in your graveyard has flashback. The flashback cost is equal to that card's mana cost plus “Pay X life, where X is this card's mana value.”

Whenever Sower of Sabne's Harvest enters or attacks, align X, where X is your fealty to Forests. (Choose modes with total ★ less than or equal to the number of Forests you control. You may choose modes multiple times.)
• ★★ — Put a +1/+1 counter on target creature.
• ★★★ — Exile target artifact or enchantment.
• ★★★★★ — You gain 5 life.

{T}: For each color among enchantments you control, add one mana of that color.
{2}{G}{G}, Sacrifice Sower of Seeds: Shuffle any number of enchantment cards from your graveyard into your library. Create an X/X black Horror creature token, where X is the number of enchantment cards shuffled into your library this way.

Manifest all cards from all players' hands. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Gestalt (When this or another creature enters under your control, you may merge it with the one in play, keeping counters and attachments. They become the permanent on top plus all abilities from under it.)
If you would gain life, you may put a +1/+1 counter on this creature instead.
When this creature has toughness 20 or greater, you win the game.

Spellwoven Monster can't be the target of spells or abilities in any zone.
As you cast an instant or sorcery spell, reveal cards from the bottom of your library until you reveal an instant or sorcery card. You may add that card's effects to that spell. Then shuffle.

Flying
If a nonland permanent an opponent controls would be returned to its owner's hand, instead gain control of it for as long as you control Sphinx Paramount.

Flying, ward {3}
Whenever Sphinx of Myriad Futures attacks, look at the top three cards of your library and reveal one of them. The defending player may have you put the revealed card into your hand. If they don't, put the other two cards into your hand. Then put the remaining cards into your graveyard.

When Spirit of the Falls enters, choose a permanent type. Return all other permanents of the chosen type to their owner's hands.
Discard two land cards: Spirit of the Falls gains hexproof until end of turn.

Whenever you gain life, put a +1/+1 counter or loyalty counter on up to that many target permanents.
Whenever you cast a white spell, create a 1/1 white Cleric creature token with lifelink.

Once during each of your turns, when you sacrifice a creature, enchantment, or planeswalker, you may choose one —
• Search your library for a card that shares a card type with the sacrificed permanent, reveal it, put it into your hand, then shuffle.
• Target opponent sacrifices a permanent that shares a card type with the sacrificed permanent.

Lifelink
When Stalked Healer enters, investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

Flying
Whenever Starborne Hellkite attacks, choose two—
• Starborne Hellkite deals 4 damage to any target.
• Destroy target artifact or land.
• Creatures you control get +2/+0 until end of turn.

Shimmer (Whenever this creature attacks, create a tapped and attacking token that's a copy of it. Exile the token at the beginning of the end step.)
Each other creature you control gets +1/+1 for each creature you control with the same name as it. (A token's name is its creature types unless specified.)

Flying, haste
Whenever you cast an instant or sorcery spell, create a token that's a copy of Stormcall Thunderbird.

If you would lose the game, instead sacrifice a storied permanent. If you do and your life total is less than 1, it becomes 1.

Menace (This creature can't be blocked except by two or more creatures.)
Civilized — Whenever Subjugator of Empires attacks, if you control an artifact, a creature, and an enchantment, each opponent discards a card, sacrifices a creature, and loses 3 life.

[+1]: Each opponent loses 1 life for each card you've drawn this turn. Then you draw a card.
[–2]: Sun King's Shadow deals 2 damage to target creature or planeswalker and you gain 2 life. If that permanent was already dealt damage this turn, destroy it.
