Primal {1}{W}{W} (During your turn, you may cast this spell for {1}{W}{W} instead of playing a land.)
Return target creature card from your graveyard to the battlefield.

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.

Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard.
Flashback {3}{U} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Look at the top two cards of your library. Put one into your graveyard and the other back on top.

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.”

[+2]: Each player sacrifices a creature. Then each player who did creates a 1/1 white and black Spirit enchantment creature token.
[–X]: You may put an enchantment card with mana value X or less from your hand onto the battlefield.
[–6]: Shuffle, then reveal the top seven cards of your library. Put any number of enchantment cards from among them onto the battlefield. Shuffle the rest into your library.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you draw a card from the archived library, put the top card of your main library on the bottom of the archived library.
{U}: Exchange a card from the archived library with a card from your hand.

As an additional cost to cast this spell, discard a land card.
Draw two cards.

{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.”)

{1}{W}: Target creature you control gets +0/+1 until end of turn and assigns combat damage equal to its toughness rather than its power this turn. When that creature deals combat damage to a player this turn, transform Reversal Medic.

Counter target spell. Its controller draws a card.

Destroy target artifact, enchantment, or creature with flying.
