Exile the bottom four cards of your library. Return a creature or enchantment card from among them to your hand. You gain life equal to its mana value.

Destroy all creatures, then return all nonland permanents to their owner's hands.

When Return to the Home Plane enters, draw a card, then choose a card name.
Spells you cast with the chosen name cost {G/U}{G/U} less to cast and may be cast as though they had flash. This effect reduces only the amount of colored mana you pay.

Destroy up to one target artifact, enchantment, or creature with flying. Create two 1/1 green Saproling creature tokens.

Enspirit (As you cast this spell, you may exile a nonenchantment creature you control until this leaves the battlefield or fails to resolve. Reduce this spell's cost by the exiled card's mana value.)
When Returned Bokor dies, return it to its owner's hand.

At the beginning of your upkeep, if a library has twenty or fewer cards left in it, return Returned Explorer from your graveyard to the battlefield tapped.

As long as there are three or more creature cards in your graveyard, Returned Minotaur gets +1/+1 and has menace.

Persist (When this creature dies, if it had no -1/-1 counters on it, return it to the battlefield under its owner's control with a -1/-1 counter on it.)

As an additional cost to cast Reunite with Nature, sacrifice X creatures.
Create X plus one 3/1 red and green Elemental Horror creature tokens with haste and trample.

Lifelink
{W}{B}, {T}, Discard a card: Look at the top three cards of your library. You may reveal an enchantment card from among them and put it into your hand. Put the rest on the bottom of your library in any order.
When you have no cards in hand, exile Revela, then return her to the battlefield transformed under her owner's control.

[+1]: Creatures you control get +1/+0 and gain respawn until end of turn. (When one dies, if it attacked this turn, return it to its owner's hand.)
[0]: You get an emblem with “Whenever a creature you control attacks, you gain 1 life.”
[–5]: Until end of turn, Revela becomes a legendary Human Cleric Avatar creature with lifelink, indestructible, and “This creature's power and toughness are each equal to your life total.”

{B}: Revenant Shade gets +1/+1 until end of turn.

Destroy target creature. Investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

Foretell {3}{G} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
This spell's foretell cost costs {3} less to pay if an opponent drew two or more cards this turn.
Create a 5/5 green Beast creature token with trample.

When Reverence Seeker dies, you may return another target Knight card from your graveyard to your hand.

Reverent Flame deals 3 damage to target creature. Create three Idol tokens. (They're artifacts with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

Shuffle your graveyard into your library, then draw two cards.

This spell can't be countered.
Exile your library, then shuffle Revisionary Studies, your graveyard, and your hand into your library. Draw five cards.

Flying
Whenever Revived Pterosaur deals combat damage to an opponent, that player discards a card.
{4}{B}{B}, Discard two cards: Return Revived Pterosaur from your graveyard to the battlefield tapped.

Exile target nonbasic permanent. Search any number of graveyards, hands and libraries for any number of cards with the same name as that permanent and exile them. Then each player shuffles their libraries searched this way.

Enchant creature
Enchanted creature can't attack, block, or crew Vehicles.

Deploy 4 (As this enters, you may tap any number of other creatures you control with total power 4 or more.)
When Revolutionary Recruiters enters deployed, gain control of target creature until end of turn. Untap that creature. It gains haste until end of turn.

Choose target spell. If it's an instant, a sorcery, or you cast this spell from exile, copy it. You may choose new targets for the copy.
Prophecy {2}{U}{U} (Once each turn, you may exile a card with prophecy as you reveal it. When you do, you may cast it for its prophecy cost as long as it's exiled.)

When Rework the Canvas enters, purge. (Exile two cards that share a type from graveyards. If you do, draw a card.)
Whenever one or more cards are put into exile from anywhere, you gain 2 life and scry 1.

Ward {2}
When Rewriter of Flesh enters, target creature you control becomes an enchantment and loses all other card types. (It still has its abilities, but it's no longer a creature.)
