Control of Another Player

You have accumulated 7+ counters on Sorin and you intend to activate his ultimate ability (it’s a colloquial name for a planeswalker’s last ability). You need to imagine very well what you will be doing and what you may not do.

712. Controlling another player


712.1. Some cards allow a player to control another player during that player’s next turn. This effect applies to the next turn that the affected player actually takes. The affected player is controlled during the entire turn; the effect doesn’s end until the beginning of the next turn.

712.1a. Multiple player-controlling effects that affect the same player overwrite each other. The last one to be created is the one that works.

712.1b. If a turn is skipped, any pending player-controlling effects wait until the player who would be affected actually takes a turn.

712.2. One card (Word of Command) allows a player to control another player for a limited duration.

712.3. Only control of the player changes. All objects are controlled by their normal controllers. A player who’s being controlled during his or her turn is still the active player.

712.4. If information about an object would be visible to the player being controlled, it's visible to both that player and the controller of the player.

Example: The controller of a player can see that player's hand and the face of any face-down creatures he or she controls.

712.5. While controlling another player, a player makes all choices and decisions the controlled player is allowed to make or is told to make by the rules or by any objects. This includes choices and decisions about what to play, and choices and decisions called for by spells and abilities.

Example: The controller of another player decides which spells that player casts and what those spells target, and makes any required decisions when those spells resolve.

Example: The controller of another player during his or her turn decides which of that player’s creatures attack, which player or planeswalker each one attacks, what the damage assignment order of the creatures that block them is (if any of the attacking creatures are blocked by multiple creatures), and how those attacking creatures assign their combat damage.

Briefly: While controlling another player, you choose the value of X for that player’s Aurelia's Fury, the modes of his Cryptic Command, whether he spends life or mana to cast Phyrexian Metamorph, and which cards he will reveal as Gifts Ungiven resolves.

712.5a. The controller of another player can use only that player’s resources (cards, mana, and so on) to pay costs for that player.

Example: If the controller of a player decides that the controlled player will cast a spell with an additional cost of discarding cards, the cards are discarded from the controlled player’s hand.

Comment: if you make that player cast a spell, and as an additional cost to cast that spell a creature must be sacrificed, you must choose the creature under that player’s control. And, obviously, you may only use the resources of only that player to pay the costs, not your own.

712.5b. The controller of another player can’s make choices or decisions for that player that aren’s called for by the rules or by any objects. The controller also can’s make any choices or decisions for the player that would be called for by the tournament rules.

Example: The player who’s being controlled still chooses whether he or she leaves to visit the restroom, trades a card to someone else, agrees to an intentional draw, or calls a judge about an error or infraction.

712.6. The controller of another player can’s make that player concede. A player may concede the game at any time, even if he or she is controlled by another player. See rule 104.3a.

712.7. The effect that gives control of a player to another player may restrict the actions the controlled player is allowed to take or specify actions that the controlled player must take.

712.8. A player who controls another player also continues to make his or her own choices and decisions.

712.9. A player may gain control of himself or herself. That player will make his or her own decisions and choices as normal.

As per Tournament rules, a small detail is of great importance to us here:

3.15 Sideboard

During a game, players may look at their own sideboard, keeping it clearly distinguishable from other cards at all times. If a player gains control of another player, he or she may not look at that player’s sideboard, nor may he or she have that player access his or her sideboard.

Therefore, while controlling another player’s turn, you may not look into his or her Sideboard. And the Wishes card cycle may not bring a card that’s outside the game into the game.

In formats where more than 2 players participate in a game with a shared turn for a team of several players, a player controlling another player controls the entire team of that player.

For instance, in Two-Headed Giant:

805.8. (...) If an effect causes a player to control another player, the controller of that effect controls the affected player’s team.

Homework

During your turn, an opponent has played a Summoner’s Pact which resolved successfully. Later during that turn you have activated Sorin Markov’s third ability which also resolved successfully. The opponent’s turn begins, in which you control him. What happens?

Sorin MarkovSummoner's Pact

You are playing in a tournament at Competitive Rules Enforcement Level. You are at 15 life. During your turn, you activate Mindslaver’s ability targeting your opponent. The ability resolves. At the beginning of the next turn you forget about the enemy Vampire Lacerator’s trigger and do not reduce life. A judge passing by is eager to punish someone for this. Who will be punished and how?
