When Chamber of Penance enters, exile target nonland permanent an opponent controls until Chamber of Penance leaves the battlefield.

At the beginning of each upkeep, choose one or more —
• Untap target artifact.
• Untap target creature.
• Untap target land.

When Festering Shipwreck enters, create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)
At the beginning of each player's upkeep, that player sacrifices a nonland permanent.

Draw three cards, then you may submerge a card from your hand. (To submerge a card, exile it, then put it on the battlefield face down under its owner's control as a 2/2 creature.)

Cards in graveyards lose all abilities.
Cards in graveyards can't be the target of spells or abilities.

For each permanent type, you may put a permanent card of that type from your hand onto the battlefield. Exile Set the Stage.

As an additional cost to cast this spell, sacrifice a creature.
Search your library, hand, or graveyard for a creature card with mana value 1 greater than the sacrificed creature's and put it onto the battlefield. If you searched your library this way, shuffle.

{T}: Add {C}.
{T}, Pay 1 life: Add {G}.
{G}, {T}: Add one mana of any color.

Rapport — Whenever Aelinn, Serpent's Voice and at least one other creature you control become tapped, reveal the top card of your library. You may cast that card. If you don't, put it into your graveyard and Aelinn, Serpent's Voice deals 2 damage to each opponent.

Adorned — Commoners' Favored gets +2/+2 as long as it's equipped and/or enchanted.

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.

Golden age (If you cast an instant or sorcery spell, activated a nonmana ability, and attacked this turn, enter a renaissance for this game.)
Whenever a Demon you control enters, put a +1/+1 counter on Tzelin.
{2}{B}: Sacrifice Tzelin. If you do, each opponent loses life equal to Tzelin's power. If you're in a renaissance, also draw that many cards.

Thriving Isle enters tapped.
As Thriving Isle enters, choose a color other than blue.
{T}: Add {U} or one mana of the chosen color.

Speckled Outcast has menace as long as it's enchanted.

Enchant creature
When Crown of Spores enters, germinate. (Put a +1/+1 counter on a creature or create a 1/1 green Saproling creature token.)
Enchanted creature gets +2/+2.

Puzzlebox (Begin the game with this and another card you own from outside the game in the command zone, locked. That card is face down until you unlock this.)
{0}: Unlock Tesseract Conjecture. If the revealed card shares a mana value with three or more permanents you control, cast it without paying its mana cost.

Spells can't be cast from libraries.
If a nonland permanent would enter from a library, exile it instead.

All lands gain “{T}: Add one mana of any color” and lose all other abilities.

{3}{B}, Exile Screeching Duneborn from your graveyard: You gain 1 life and draw a card.

First strike
Whenever Martial Maestro attacks, other attacking creatures you control get +1/+0 until end of turn.

{2}, Sacrifice another creature: 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.”)

Enchant creature
Enchanted creature gets +4/+4 and has trample.
When enchanted creature dies, create a 4/4 green Beast creature token with trample.

When Fireheart Channeler dies, you may exile it. If you do, put a blaze counter on target land without a blaze counter on it. As long as that land has a blaze counter on it, it has “At the beginning of your upkeep, this land deals 1 damage to you.” (The land continues to burn after Fireheart Channeler has left the battlefield.)

Flash
Flying
Whenever you cast another spell with flash or an instant, conjure a card named Data-Point into your hand. (It's a sorcery that costs {2} with “Draw a card.”)

Equipped creature gets +2/+0.
Equipped creature has first strike as long as it's attacking.
Equip {2}
