Legacy (You may play this side of this card only from your graveyard. Exile it if it would be put into a graveyard or not resolve.)
Target Warrior you control deals damage equal to its power to target creature an opponent controls.

Relonche Spy enters under the control of an opponent of your choice.
Relonche Spy can't block.
During each of Relonche Spy's owner's turns, they may cast a card from your graveyard by paying life equal to its mana value rather than paying its mana cost.

Choose a creature. Exile the rest.

Return target instant or sorcery card from your graveyard to your hand.
Leitmotif (If you cast this spell from your hand, exile it as it resolves. When you next cast a spell that shares a color with this card, you may cast this from exile without paying its mana cost.)

Mill three cards. Return a card from among the milled cards to your hand. Then shuffle three cards from graveyards into their owners' libraries.

Flash
When Remnant Spotter enters, put target permanent card from your graveyard on top of your library.

Trample
When Remnant of the Wild enters, if you cast it, untap all lands you control.

When Renatured Vines enters, draw a card and create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)
Renatured Vines power and toughness are each equal to the number of cards in your hand.

Destroy target creature or planeswalker. You gain 1 life and that permanent's controller loses 1 life.

Choose four nonland card names. Target opponent reveals their hand and discards all cards with the chosen names.

{T}, Sacrifice Renewal Grove: Search your library for a basic land card, put it onto the battlefield, then shuffle. If Renewal Grove entered since your last upkeep, that land doesn't untap during your next untap step.

Exchange control of two target creatures. If an opponent gained control of a Monk you controlled this way, return that creature to its owner's hand.

Flash (You may cast this spell any time you could cast an instant.)
When Replicator Mage enters, you may create a token that's a copy of target creature that's attacking you. Exile that token at end of combat.

Flash
If a player would conjure a card, they instead conjure a card named Data-Point. (It's a sorcery that costs {2} with “Draw a card.”.)
If a player would copy a spell or cast a copy, they copy the card named Data-Point instead of anything else.

When Reprising Bard enters, exile target instant or sorcery card with mana value 3 or less from your graveyard. When Reprising Bard is no longer on the battlefield, copy the exiled card. You may cast the copy without paying its mana cost.

Whenever a creature you control dies, you may search your library for an enchantment card or a card with fabled, reveal it, put it into your hand, then shuffle.

Whenever another creature you control enters, you may change Reshaping Primordial's base power and toughness to that creature's power and toughness.

Each opponent mills half their library, rounded up. When they do, return target creature card from a graveyard to the battlefield under your control.

Whenever a land you control enters, you may sacrifice a creature. If you do, each opponent sacrifices a creature.
{2}{B}{G}, Sacrifice a land: Draw a card.

Choose target instant spell, sorcery spell, activated ability, or triggered ability. Create a Function token with its effects. Then you may pay {1}{U}. If you do, counter that spell or ability. (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell. A spell's effects includes added functions.)

Return target nonland permanent to its owner's hand. Then you may pay {U}{U}. If you do, copy Resonating Force and you may choose new targets for the copy.

Enchant permanent
Whenever a counter is removed from enchanted permanent, you may put a counter of that type on another target permanent.

You may cast this spell as though it had flash if you pay an additional {2} to cast it.
You may have Resourceful Impersonator enter as a copy of any creature on the battlefield.

{1}: Exile target card from a graveyard.
At the beginning of combat on your turn, if there are three or more card types among cards exiled with Respectful Tracker, put a +1/+1 counter on target creature you control.

({T}: Add {G} or {W}.)
Whenever Resplendent Substratum becomes tapped, you lose 1 life unless you control two or more basic lands.
