Each opponent sacrifices a creature. For each creature sacrificed this way, create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

At the beginning of your end step, shuffle your hand and graveyard into your library, then draw seven cards.

Vigilance
{X}{G}, {T}: Ylda, the Wild Soul becomes a copy of target creature you control with mana value X, except it has this ability and vigilance. Activate only as a sorcery.

When Ragantiar enters, mill five cards.
{3}{B}, Sacrifice a creature: Return target creature card with power X or less from your graveyard to the battlefield, where X is 1 plus the sacrificed creature's power.

Look at the top five cards of your library. You may reveal a Scout or land card from among them and put it into your hand. Put the rest on the bottom of your library in any order.

As Ritual Preparations enters, choose a color.
You don't lose unspent mana of the chosen color as steps and phases end.

{T}: Add {R} or {W}.
{T}, Sacrifice Sigil of Brutality: Add {R}{W}.

When Limited Mortality enters, return up to one target creature card from your graveyard to your hand.
{1}{B}, Sacrifice Limited Mortality: Return target creature card from your graveyard to your hand. Activate only as a sorcery.

You may have Insipid Metamorph enter as a copy of any other creature on the battlefield, except it's 1/1.

Haste
At the beginning of each end step, put a +1/+1 counter on Rahstahde's Swiftspear if you cast a noncreature spell this turn.
Surpass {5}{R} ({5}{R}: Transform this creature. This costs {1} less to activate for each counter on it. Activate only as a sorcery.)

Whenever you cast an instant or sorcery spell from your hand, you may cast target card with the same name as that spell from your graveyard. (You still pay its costs.)

First strike
Wither (This deals damage to creatures in the form of -1/-1 counters.)

Whenever one or more Rogues you control attack, you may pay 1 life. If you do, draw a card.

When Prince Crab enters, create a Treasure token and an Idol token. (An artifact with “{T}, Sacrifice this artifact: Add one mana of any color” and an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

When Twilight Vigil enters, scry 2, then put a night counter on it.
Death knell — Put a night counter on Twilight Vigil. (As a creature you control dies, trigger one death knell of that creature or another permanent you control.)
Sacrifice Twilight Vigil: For each night counter on it, you gain 1 life and trigger up to one death knell of a permanent you control.

Until end of turn, gain control of target creature and it gains haste. Untap it.
Fuse (You may cast one or both halves of this card from your hand.)

Haste
Battalion — Whenever Fellor Tactician and at least two other creatures attack, creatures you control get +1/+1 until end of turn.

Put a +1/+1 counter on each creature you control. (Then exile this card. You may cast the creature later from exile.)

Whenever Cloudfisher deals combat damage to a creature, gain control of that creature for as long as you control Cloudfisher.
Whenever Cloudfisher deals combat damage to a player, gain control of target land that player controls for as long as you control Cloudfisher.

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 you draw a card from the archived library, target opponent loses 3 life unless they discard a card or sacrifice a nonland permanent.

Creature cards in your graveyard have revive. The revive cost is equal to their mana cost. (Pay that creature's mana cost, Exile that card from your graveyard: Create a token that's a copy of it except it has no mana cost. Revive only as a sorcery.)

Whenever Icepeak Phantasm becomes the target of a spell or ability, an opponent may pay {2}. If they do, sacrifice it.
