Equivalent cards to Opposition Agent (black, disruptive, affects searching libraries):
1. Aven Mindcensor (white) – Limits opponents' library searches to top four cards.
2. Leonin Arbiter (white) – Players can't search libraries unless they pay mana.

    Rules

  • After the search is complete, the entire library is shuffled.
  • Each search works exactly the same as normal except that the opponent doing the searching sees only the top four cards of that library. They can't look at the other cards in that library at all. Cards not in the top four cards of the library can't be found in the search, even if they're identifiable in some manner.
  • For effects that check whether a player searched a library or may search a library, searching the top four cards of that library counts as searching that library.
  • If an effect uses the word "search" once but allows an opponent to search for multiple cards, the top four cards remain the same throughout the entire search. Finding one card won't cause the fifth card to become included in the search.

    Rules

  • A player who has paid {2} may search any library when instructed to do so that turn, not just their own library.
  • Effects that instruct you to reveal or look at cards from the top of you library will still work. Only effects that use the word "search" are affected.
  • If a player pays {2}, that enables only them to ignore Leonin Arbiter's effect that turn. Each other player is still affected by it.
  • If an effect says "Search your library . . . then shuffle your library," you shuffle you libraries even though you can't search.
  • If an effect says "You may search your library . . . If you do, shuffle your library" or "You may search your library . . . then shuffle your library," you can't choose to search, so you won't shuffle.
  • If there are multiple Leonin Arbiters on the battlefield, a player must pay {2} for each one before being able to search libraries that turn.
  • Once a player has paid {2}, they may search libraries that turn as many times as they are instructed to do so.
  • Paying {2} doesn't let a player pick up a library and search it — it just allows them to ignore Leonin Arbiter's effect that turn. That player can search a library only if another spell or ability instructs them to do so.
  • Paying {2} to ignore Leonin Arbiter's effect is a special action. Any player may take this special action any time they have priority. It doesn't use the stack and can't be responded to.
  • Since players who haven't paid {2} can't search, they won't be able to find any cards in a library. The effect applies to all players and all libraries. If a spell or ability's effect has other parts that don't depend on searching for or finding cards, they will still work normally.

    Rules

  • In a Two-Headed Giant game, Maralen’s triggered ability will trigger twice per draw step (once for each player on the active team). Maralen’s controller chooses the order to put the abilities on the stack.
  • Maralen prevents players from drawing cards for any reason, including as a cost, as an effect, and as a result of the “draw a card” turn-based action during the draw step.
  • The effect of the triggered ability is mandatory. The life loss isn’t a payment; you’ll lose 3 life even if you have 3 or less life left. Unless your library is empty, you must put a card from your library into your hand.
  • While Maralen is on the battlefield, a player can’t choose to draw cards (or choose to have another player draw cards) as a spell or ability resolves. For example, if you cast the Development side of Research // Development (“Put a 3/1 red Elemental creature token onto the battlefield unless any opponent lets you draw a card. Repeat this process two more times.”), you’ll put three Elemental tokens onto the battlefield because your opponents can’t “let you draw a card.”
  • While Maralen is on the battlefield, no player can lose the game due to being instructed to draw a card with an empty library.
  • While Maralen is on the battlefield, replacement effects that instruct a player to do something instead of drawing a card won’t work.

    Rules

  • If a spell or ability instructs an opponent you control to search multiple zones including the library, you decide what cards they find in all zones. They'll exile all cards they find in any of the zones.
  • If more than one player controls an Opposition Agent, and another player searches their library, the controller of the Opposition Agent that most recently entered the battlefield controls that player during the search. Because the last ability of each Opposition Agent is trying to exile the card and give permission to play it, the owner of the exiled card chooses which effect wins. However, that owner will be under another player's control, so that player controlling that owner actually makes the decision. In other words, the player who controls the Opposition Agent whose effect applies (and thus controls the opponent) can choose to give themselves all the play permissions unless they're feeling very generous.
  • If the search instruction states a quality of the card to find, such as a color or card type, you may have the opponent not find any cards. If the search is simply for a number of cards without stating a quality, you must have them find that many cards (or as many as possible, if their library doesn't contain that many cards).
  • In a multiplayer game, if a player leaves the game, all cards that player owns leave as well.
  • The cards found in the search will be exiled rather than be put wherever the spell or ability tells the opponent to put them after finding them. Any other effects the spell or ability has will still apply. If such an effect refers to the found cards, it can't see them in exile.
  • While controlling an opponent, you can't make any choices or decisions for that player related to tournament rules. You can't make them concede or have them agree to an intentional draw.
  • While controlling an opponent, you make all choices and decisions for that player. However, because the control effect is limited to while they're searching their libraries, it's unlikely the player will be allowed to make any decisions other than what to find with the search.
  • You can't have the player find cards in their library that aren't asked for by the search instruction. For example, if the opponent is searching their library for a basic land card, you can't have them find a different card, such as a creature card.
  • You must follow the normal timing permissions and restrictions for each exiled card. If one is a land, you can't play it unless you have land plays available.
  • You'll still pay all costs for a spell cast this way, including additional costs. You may also pay alternative costs if any are available.

    Flash You control your opponents while they're searching their libraries. While an opponent is searching their library, they exile each card they find. You may play those cards for as long as they remain exiled, and you may spend mana as though it were mana of any color to cast them.
