Rule 117.3 in Magic: The Gathering is a cornerstone of the game’s intricate timing and priority system. Simply put, it outlines what happens when a player takes an action that could potentially be responded to. It consists of two key sub-rules: 117.3c states that if a player has priority when they cast a spell, activate an ability, or take a special action, that player receives priority afterward. 117.3d states that if a player has priority and chooses not to take any actions, that player passes. If any mana is in that player’s mana pool, they announce what mana is there. Understanding this rule is essential for navigating complex game states and making informed decisions.
Why Priority Matters
The concept of priority might seem abstract, but it’s the engine that drives the resolution of spells and abilities in Magic. Think of priority as the right to act first. Only the player with priority can cast spells, activate abilities, or take special actions (like conceding!). This system ensures that players have opportunities to respond to each other’s actions, leading to strategic interplay and dynamic gameplay. Rule 117.3 specifically deals with what happens after a player takes one of these actions, setting the stage for the next sequence of choices.
Deconstructing 117.3c: The Active Player’s Advantage
Let’s break down the first part of the rule: 117.3c. This rule is critical, especially for the active player (the player whose turn it is). Imagine the active player casts a powerful sorcery. According to 117.3c, after casting that sorcery, the active player retains priority. This is huge! It means they have the option to cast another spell, activate an ability, or even take a special action before their opponent gets a chance to react to the first sorcery.
This ability to “hold priority” opens up a world of possibilities for strategic plays. For example, the active player could cast a second spell that benefits from the effect of the first, or they could activate an ability that protects the first spell from being countered.
Deconstructing 117.3d: Passing and Mana Pools
The second part of the rule, 117.3d, deals with passing priority. When a player has priority and doesn’t want to do anything, they pass priority to the next player in turn order (usually the opponent). This signals that they are content with the current game state and are ready for the next player to act. An important side note: if the player has mana floating in their mana pool, they must announce the type and amount of mana they have before passing. This is relevant because mana pools empty between steps and phases, so the opponent needs to be aware of any potential plays the player could make with that mana before it disappears.
Examples in Action
Let’s look at some practical examples to illustrate how Rule 117.3 works:
- Scenario 1: Holding Priority for a Combo: You cast a creature spell, and before your opponent can respond with a removal spell, you activate an ability of another creature you control that puts +1/+1 counters on the first creature. You’ve “held priority” to make your creature bigger before it can be killed.
- Scenario 2: Triggering Multiple Abilities: You cast a spell that triggers multiple abilities you control. You can order these triggers on the stack in a way that benefits you most. You retain priority after casting the initial spell and placing the triggers on the stack.
- Scenario 3: Passing and Letting a Spell Resolve: You cast a spell, and your opponent doesn’t respond. You pass priority, and because your opponent also passes, your spell resolves.
Common Mistakes and Misconceptions
One common mistake is assuming that casting a spell automatically gives your opponent a chance to respond. While it’s true that your opponent will eventually get priority, you have the opportunity to take additional actions first. Another misconception is thinking that “holding priority” is the default. It’s not; you must explicitly announce that you are holding priority. Otherwise, it’s assumed you are passing priority to the next player.

Frequently Asked Questions (FAQs) about Rule 117.3
Here are some frequently asked questions regarding the intricacies of rule 117.3:
1. Can I respond to my own spell?
Yes, absolutely! Because you retain priority after casting a spell, you can cast another spell or activate an ability targeting your own spell while it’s on the stack. This can be used to protect it or enhance its effect.
2. What happens if I forget to announce I’m holding priority?
In most casual settings, your opponent will likely give you the benefit of the doubt if it’s clear you intended to hold priority. However, in more competitive environments, it’s crucial to be explicit. The judge may rule that you have passed priority.
3. Can I hold priority during my opponent’s turn?
No, you can’t hold priority during your opponent’s turn. After they take an action, they must pass priority to you. You can then respond, but you cannot retain priority after your response.
4. Does tapping a land require passing priority?
Tapping a land for mana is a mana ability, which doesn’t use the stack and cannot be responded to. Tapping a land for mana doesn’t inherently force another round of priority, but if you use that mana to cast a spell or activate an ability, the normal priority rules apply.
5. If I cast a spell with split second, can I still hold priority?
You can hold priority and cast a spell with split second. However, once the split second spell is on the stack, players cannot cast other spells or activate abilities except for mana abilities.
6. What’s the difference between “responding” and “holding priority”?
Responding is when you take an action after your opponent has already taken one and passed priority to you. Holding priority is when you take an action without passing priority to your opponent.
7. How do state-based actions interact with priority?
State-based actions are checked and performed before a player would receive priority. This means if a state-based action would cause a spell or ability on the stack to become an illegal target, it will be removed from the stack before any player can respond to it.
8. Can I use priority to cast multiple spells before my opponent gets a chance to act?
Yes, you can cast as many spells as you have mana and resources for, as long as you hold priority after each one. This is a common strategy in combo decks.
9. What happens if multiple players want to respond to the same spell?
The active player (the player whose turn it is) gets to add their response to the stack first. Then, each other player in turn order can add their response to the stack, if they choose.
10. Is “passing priority” the same as saying “I’m done”?
Not necessarily. Passing priority only means you don’t want to take any action at that moment. You might have other cards in hand and be waiting for your opponent to make a move before deciding what to do.
11. Can I respond to a mana ability?
No, mana abilities don’t use the stack and cannot be responded to. This is why tapping lands for mana is an instantaneous action.
12. How does priority work with triggered abilities?
Triggered abilities automatically go on the stack when their trigger condition is met. The active player puts all their triggered abilities on the stack first, in any order they choose. Then, each other player in turn order puts their triggered abilities on the stack. Players only get priority after all triggered abilities have been placed on the stack.
13. Can I hold priority indefinitely?
No, you can’t hold priority indefinitely. Eventually, you must either take an action or pass priority. Holding priority and not doing anything would stall the game.
14. Does rule 117.3 apply to all types of actions in Magic?
Rule 117.3 specifically applies when casting a spell, activating an ability, or taking a special action. Other actions, like drawing a card or going to the next phase, have their own specific rules regarding priority.
