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.

Equipped creature gets +2/+2, has haste, can't attack you or planeswalkers you control, and can't be sacrificed.

At the beginning of each opponent's upkeep, you may have that player gain control of equipped creature until end of turn. If you do, untap it.

Equip {3}

{3}: You may put a Minotaur permanent card from your hand onto the battlefield.

Exile all permanents. For as long as any of those cards remain exiled, at the beginning of each player's upkeep, that player returns one of the exiled cards they own to the battlefield.

Rather than pay the mana cost for a spell, its controller may discard a card that shares a color with that spell.

Each creature has "When this creature dies, choose target opponent. That player puts this card from its owner's graveyard onto the battlefield under their control at the beginning of the next end step."

Players skip their upkeep steps.

At the beginning of your upkeep, for each land target player controls in excess of the number you control, choose a land that player controls, then the chosen permanents phase out. Repeat this process for artifacts and creatures. (While they're phased out, they're treated as though they don't exist. They phase in before that player untaps during their next untap step.)

Exile target nonland permanent. Each player other than its controller creates a token that's a copy of it.

Cumulative upkeep {2} (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.)

When Illusions of Grandeur enters the battlefield, you gain 20 life.

When Illusions of Grandeur leaves the battlefield, you lose 20 life.

You may choose not to untap Immovable Rod during your untap step.

Whenever Immovable Rod becomes untapped, venture into the dungeon.

{3}{W}, {T}: For as long as Immovable Rod remains tapped, another target permanent loses all abilities and can't attack or block.

Imprint -- When Knowledge Pool enters the battlefield, each player exiles the top three cards of their library.

Whenever a player casts a spell from their hand, that player exiles it. If the player does, they may cast a spell from among other cards exiled with Knowledge Pool without paying its mana cost.

If you would lose the game, instead shuffle your hand, your graveyard, and all permanents you own into your library, then draw seven cards and your life total becomes 20.

{T}, Sacrifice Mirror of Fate: Choose up to seven face-up exiled cards you own. Exile all the cards from your library, then put the chosen cards on top of your library.

When Spark Rupture enters the battlefield, draw a card.

Each planeswalker with one or more loyalty counters on it loses all abilities and is a creature with power and toughness each equal to the number of loyalty counters on it.

At the beginning of each player's draw step, that player puts the cards in their hand on the bottom of their library in any order, then draws that many cards.

At the beginning of each player's upkeep, that player chooses artifact, creature, land, or non-Aura enchantment. All nontoken permanents of that type phase out. (While they're phased out, they're treated as though they don't exist. Each one phases in before its controller untaps during their next untap step.)

{5}, {T}: Shuffle your library, then reveal the top card. Until end of turn, for as long as that card remains on top of your library, play with the top card of your library revealed and you may play that card without paying its mana cost. (If it has X in its mana cost, X is 0.)

You don't lose the game for having 0 or less life.

When you have 20 or more life, you lose the game.

Whenever you lose life, you gain 2 life for each 1 life you lost. (Damage dealt to you causes you to lose life.)

Enchant land

When Wellspring enters the battlefield, gain control of enchanted land until end of turn.

At the beginning of your upkeep, untap enchanted land. You gain control of that land until end of turn.

At the beginning of each player's upkeep, that player reveals a card at random from their hand. If it's a land card, the player puts it onto the battlefield. Otherwise, the player casts it without paying its mana cost if able.
