Delirium — This creature can't attack or block unless there are four or more card types among cards in your graveyard. At the beginning of your upkeep, you may mill a card. (You may put the top card of your library into your graveyard.)

Lifelink Delirium — At the beginning of your end step, if there are four or more card types among cards in your graveyard, each opponent may sacrifice a nonland permanent of their choice or discard a card. Then this creature deals damage equal to its power to each opponent who didn't sacrifice a permanent or discard a card this way.

Delirium — Whenever this creature enters or attacks, if there are four or more card types among cards in your graveyard, distribute two +1/+1 counters among one or two target creatures. Then if there are six or more card types among cards in your graveyard, double the number of +1/+1 counters on those creatures.

Impending 5—{1}{B} (If you cast this spell for its impending cost, it enters with five time counters and isn't a creature until the last is removed. At the beginning of your end step, remove a time counter from it.) Whenever this permanent enters or attacks, mill four cards, then you may return a non-Avatar creature card or a planeswalker card from your graveyard to your hand.

Flying, lifelink Ward—Sacrifice three nonland permanents. If a card you didn't control would be put into an opponent's graveyard from anywhere, exile it instead. During your turn, you may play cards exiled with Valgavoth. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.

At the beginning of your upkeep, surveil 1. {2}{B}{G}, {T}, Sacrifice this artifact: Return target creature or Vehicle card from your graveyard to the battlefield. Activate only as a sorcery.

Start your engines! (If you have no speed, it starts at 1. It increases once on each of your turns when an opponent loses life. Max speed is 4.) When this enchantment enters, each opponent sacrifices a creature or Vehicle of their choice. Each opponent who can't discards a card. {2}, Sacrifice this enchantment: You gain life equal to your speed.

Whenever one or more artifact and/or creature cards leave your graveyard, you gain 1 life. When this enchantment enters, mill four cards. You may put an artifact, creature, or land card from among the milled cards into your hand. (To mill four cards, put the top four cards of your library into your graveyard.)

As an additional cost to cast this spell, discard a card or pay 3 life. Destroy target creature or planeswalker.

Kicker {1}{B} (You may pay an additional {1}{B} as you cast this spell.) Exile target artifact or enchantment. If this spell was kicked, exile target nonland permanent instead.

Target opponent reveals their hand. You choose a noncreature, nonland card from it. That player discards that card.

Choose target creature, planeswalker, or Vehicle. Mill two cards, then destroy the chosen permanent if its mana value is less than or equal to the number of cards in your graveyard.

Destroy target nonland permanent and all other permanents with the same name as that permanent.

+1: Each player discards a card. −2: Target player sacrifices a creature. −6: Separate all permanents target player controls into two piles. That player sacrifices all permanents in the pile of their choice.
