MTG Golgari Insidious Roots Deck by ipecin

This creature can't block. Whenever you commit a crime, you may pay {B}. If you do, return this card from your graveyard to the battlefield. (Targeting opponents, anything they control, and/or cards in their graveyards is a crime.)

When this creature enters or dies, mill three cards. (Put the top three cards of your library into your graveyard.)

{T}: Mill a card. (Put the top card of your library into your graveyard.) {T}, Exile a card from your graveyard: Add one mana of any color.

When this creature enters, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) {G}, Exile this card from your graveyard: Put a +1/+1 counter on target creature. Activate only as a sorcery.

{T}: Exile target land card from a graveyard. Add one mana of any color. {B}, {T}: Exile target instant or sorcery card from a graveyard. Each opponent loses 2 life. {G}, {T}: Exile target creature card from a graveyard. You gain 2 life.

{T}, Sacrifice two other creatures: Any number of target players each lose 2 life and sacrifice a creature of their choice. You add {B}{B} and draw a card.

As an additional cost to cast this spell, discard a card or sacrifice a permanent. Fathomless descent — Souls of the Lost's power is equal to the number of permanent cards in your graveyard and its toughness is equal to that number plus 1.

This creature can't block. {1}{B}, Exile another creature card from your graveyard: Return this card from your graveyard to the battlefield.

You may spend mana as though it were mana of any color to activate abilities of creatures you control. Creatures you control with +1/+1 counters on them have all activated abilities of all creature cards exiled with Agatha's Soul Cauldron. {T}: Exile target card from a graveyard. When a creature card is exiled this way, put a +1/+1 counter on target creature you control.

Creature tokens you control have "{T}: Add one mana of any color." Whenever one or more creature cards leave your graveyard, create a 0/1 green Plant creature token, then put a +1/+1 counter on each Plant you control.

Destroy target creature if it has mana value 2 or less. Revolt — Destroy that creature if it has mana value 4 or less instead if a permanent left the battlefield under your control this turn.

You may activate abilities of creatures you control as though those creatures had haste. +1: Untap up to one target creature. −2: Mill three cards, then you may return a creature card with mana value 2 or less from your graveyard to the battlefield.

If you control two or more other lands, this land enters tapped. {T}: Add {B}. {3}{B}: Until end of turn, this land becomes a 3/3 black Beholder creature with menace and "Whenever this creature attacks, exile target card from defending player's graveyard." It's still a land.

({T}: Add {B}.)

{T}: Add {B}. Channel — {3}{B}, Discard this card: Mill three cards, then return a creature or planeswalker card from your graveyard to your hand. This ability costs {1} less to activate for each legendary creature you control.

{T}: Add {G}. Channel — {1}{G}, Discard this card: Destroy target artifact, enchantment, or nonbasic land an opponent controls. That player may search their library for a land card with a basic land type, put it onto the battlefield, then shuffle. This ability costs {1} less to activate for each legendary creature you control.

({T}: Add {G}.)

This land enters tapped unless you control two or fewer other lands. {T}: Add {B} or {G}.
