At the beginning of each player's upkeep, that player discards a card. If that player has no cards in hand, instead they sacrifice a permanent. If they control no permanents, instead they lose the game.

Target creature gets -1/-1 until end of turn. (Cast a copy of this spell once while this creature is on the battlefield.)

Target creature gets +2/+2 and gains lifelink until end of turn. Whenever that creature perseveres this turn, target opponent loses 2 life. (A creature perseveres when it survives damage.)

Once during each of your turns, when you sacrifice a creature, enchantment, or planeswalker, you may choose one —
• Search your library for a card that shares a card type with the sacrificed permanent, reveal it, put it into your hand, then shuffle.
• Target opponent sacrifices a permanent that shares a card type with the sacrificed permanent.

At the beginning of your upkeep, each opponent mills two cards.
{3}{B}: Exile target nonland card from an opponent's graveyard. Copy it. You may cast the copy. Activate only as a sorcery. (You still pay its costs, including color. Copies of permanents enter as tokens.)

Enchant creature
When Sporegraft enters, germinate. (Put a +1/+1 counter on a creature or create a 1/1 green Saproling creature token.)
Enchanted creature has lifelink.

As an additional cost to cast this spell, sacrifice a permanent.
Sporesowed Disease deals 3 damage to any target and you gain 3 life.

Target creature gets -2/-2 until end of turn. When that creature dies this turn, create a tapped 2/2 black Zombie creature token.

You draw X cards and you lose X life, where X is the number of cards in your hand.

Until end of turn, if a source you don't control would deal damage to you or cause you to lose life, mill that many cards instead.

Enchant creature
Enchanted creature gets +2/+2.
Sacrifice Steady Reminiscence: Enchanted creature gains indestructible until end of turn.

Choose one or three —
• Target opponent loses 3 life.
• Return target creature card with mana value 3 or less from your graveyard to the battlefield.
• Conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

Target creature you control gains indestructible until end of turn. Whenever that creature perseveres this turn, create a 2/2 black Zombie creature token. (A creature perseveres when it survives damage.)

Choose a nonland card type. Target player reveals their hand. You choose a card of the chosen type from it. That player discards that card.

Until end of turn, creatures target player controls lose all abilities and have base power and toughness 0/2.
Inscribe {4}{B}{B} ({4}{B}{B}: Exile this card from your hand inscribed on a creature you control. Whenever that creature attacks, its controller may cast a copy of the inscribed card without paying its mana cost. Inscribe only as a sorcery.)

Mill five cards, then for each of those cards, a creature you control salvages that card unless an opponent pays 3 life. (Exile it from your graveyard until that creature leaves the battlefield. Whenever that creature deals combat damage to a player, put a card it salvaged into your hand.)

Target creature gets -3/-3 until end of turn.

Target creature gets -2/-2 until end of turn. If you control two or more Deserts, destroy that creature instead.

Stratospheric Bombardment deals X damage to any target and you gain that much life.

Each player chooses one card in their hand, then discards the rest.

Destroy target non-Assassin, non-Ninja, non-Rogue creature.

Enchant opponent
Whenever Substack Exploit or another Curse becomes attached to enchanted player, that player loses 1 life and you gain 1 life.

Destroy target untapped creature.

Destroy target tapped creature.

Target opponent reveals their hand. You choose a nonland card from it. Exile that card. You lose 2 life.
