As Enlightened Sigil enters, choose a card type.
Spells you cast of the chosen type cost {1} less to cast.

Enchant opponent
At the beginning of enchanted player's upkeep, they choose one that hasn't been chosen yet —
• They discard three cards.
• They sacrifice three nonland permanents.
• You transform Enrapturing Grudge.
If Enrapturing Grudge would be put into a graveyard from anywhere, exile it instead.

Once each turn, when you cast a spell, you may note one of its card types that hasn't been noted for Enter Captain Minnow. If you do, create a number of tapped Treasure tokens equal to the number of types noted for Enter Captain Minnow.

Whenever a Role is attached to a creature you control or you cast a spell that targets a creature you control, put a +1/+1 counter on Enthusiastic Admirer.

Artifacts you control have “{T}: Add one mana of any color.”
{2}{R}{G}: Create a 3/2 green Crocodile creature token with trample. It gains haste until end of turn.

Erupting Territory enters tapped.
{T}: Add {B} or {R}.
{1}, {T}: Add one mana of any color.

If you would search your library for one or more cards, you may search for an additional card. (It still follows the same restrictions and effects.)

At the beginning of your upkeep, return a permanent you control to its owner's hand.
You may play an additional land on each of your turns.

Trample
Evergrowing Hydra enters with X +1/+1 counters on it.
Whenever another creature you control dies, you may pay {X}, where X is less than or equal to that creature's power. If you do, put X +1/+1 counters on Evergrowing Hydra.

Vigilance
When Expendable Victim dies, create a 1/1 colorless Construct Actor creature token.

When Experienced Team enters, choose one —
• Create a 4/2 white Bear creature token.
• Create a 2/4 red Snail creature token.
• Create a 2/2 white Bird creature token with flying.

Reach
When Extolled Arachstruct enters, mill two cards. When you do, choose one —
• Each opponent sacrifices a creature with power less than the number of cards in your graveyard.
• Each opponent sacrifices a creature with power greater than the number of cards in your graveyard.

Choose one —
• The next spell you cast this turn has flash and can't be countered.
• Target creature gets +2/+0 and gains haste until end of turn.
• Target creature gets +1/+0 and gains first strike until end of turn.

{2}, {T}: Tap target creature. This ability costs {2} less to activate if you control an enchantment.

{T}, Sacrifice Fabled Passage: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. Then if you control four or more lands, untap that land.

Choose one —
• Target creature you control gets +0/+2 and gains hexproof until end of turn.
• Return target nonland permanent to its owner's hand.

{1}{W}, {T}: Aetherize target creature you control. (To aetherize, create a token that's a copy of it, then exile that token.)

Destroy target creature or planeswalker with mana value 2 or less. Create a tapped Treasure token. (It's an artifact with “{T}, Sacrifice this artifact: Add one mana of any color.”)

{T}: You may tap or untap another target permanent.
Unearth {U} ({U}: Return this card from your graveyard to the battlefield. It gains haste. Exile it at the beginning of the end step or if it would leave the battlefield. Unearth only as a sorcery.)

Faux, Who Lives for the Hunt enters as a copy of a creature card in your graveyard except it's legendary and has changeling and “When this creature dies, if it didn't have a bounty counter on it, return it to the battlefield with a bounty counter.” (It has “When this creature dies, each opponent draws a card” as long as it has a bounty counter on it.)

Flying, first strike, lifelink

When Fel Alston, Halfway Queen enters, return target creature card from your graveyard to the battlefield. Then exile that creature unless Fel Alston was cast for its escape cost.
Escape—{1}{W}{U}{B}, Sacrifice two creatures. (You may cast this card from your graveyard for its escape cost.)

Whenever a nontoken creature you control dies, create a 1/1 black Worm creature token.
Sacrifice Fertile Grave: Create a 1/1 black Worm creature token.

Whenever another nontoken creature you control dies, create a 1/1 black Rat creature token with “This creature can't block” if this is the first time this ability has resolved this turn. Otherwise, Ffion, Famine Warcaller deals 1 damage to each player.

Each player chooses a legendary permanent from among the nonland permanents they control, then sacrifices the rest.
