Declaring blockers is a critical step in the combat phase of a game like Magic: The Gathering, determining how damage will be assigned between attacking and defending creatures. In simple terms, declaring blockers involves the defending player choosing which of their untapped creatures will attempt to block incoming attacks. This action is a key decision point, often requiring careful consideration of the game state, the opponent’s potential actions, and the potential ramifications of each choice. It’s not just about assigning defenders, it’s about controlling the flow of combat and setting yourself up for success, making it a complex strategic maneuver.
The Process of Declaring Blockers
The declaration of blockers occurs after the attacking player has declared which creatures will attack. This is the beginning of the second step in the combat phase, where the defending player gets a crucial chance to mitigate some, or all, of the damage coming their way. Here’s a breakdown of the process:
-
Untapped Creatures: The defending player can only choose to block with creatures they control that are untapped. This means that if a creature is tapped for any reason – either due to an ability, or because it was used in combat previously – it cannot be declared as a blocker during that specific turn.
-
Choice of Blockers: The defending player selects their creatures to block individually. Each defending creature can block one attacking creature only. This means that a single attacking creature can be blocked by multiple defending creatures, however each blocking creature can only block one attacking creature.
-
No Attacker Block Option: There is no “block all” option, the defending player must specifically declare each of their defending creatures as a blocker.
-
Turn-Based Action: Declaring blockers is a turn-based action that does not use the stack. This means that once blockers are declared, the active player cannot respond to the declaration by casting an instant, activating an ability, etc. They receive priority after the block declaration is finished.
What Happens After Blockers Are Declared?
Once blockers have been declared by the defending player, several things occur:
-
Damage Assignment Order: For each blocked attacking creature, the attacking player announces the damage assignment order. This is the order in which the blocking creatures will be assigned damage. For example, if an attacking creature is blocked by three defending creatures, the attacking player decides which order those three defenders will receive damage. The attacking creature must assign lethal damage to the first creature in the order, then move to the next one, and so on.
-
Priority: After blockers are declared and the damage assignment order has been determined, the game progresses. Both the attacking and defending players receive priority.
-
Combat Damage Step: Following this period where spells and abilities can be used, the game moves to the combat damage step, where damage is assigned based on the attackers and blockers declared.
Key Considerations When Declaring Blockers
Properly declaring blockers is crucial for effective gameplay, so pay attention to the following:
-
Multiple Blockers: The most fundamental purpose of blocking is to keep your creatures alive, and to prevent or reduce damage to yourself or your planeswalkers. Multiple blockers against one attacker can ensure at least one of your creatures survives, or that the attacker itself is destroyed.
-
Damage Calculation: Be mindful of the attacking creature’s power and any relevant effects that could boost damage. Also note the toughness of the blocking creatures.
-
Potential Tricks: Be wary of potential instant-speed tricks that the attacking player could use. Spells, abilities or combat tricks played between the declare blockers and combat damage steps can change the result of the combat completely.
-
Resource Management: Sometimes, sacrificing a creature to block an incoming attack can be strategically beneficial, particularly to protect your life total or another valuable permanent. This is especially important when playing aggressively, trading resources to push through with your offense.
Frequently Asked Questions (FAQs) About Declaring Blockers
1. Can I respond to blockers being declared?
No, you cannot respond to blockers being declared in the same way you would to a spell cast by a player. Declaring blockers is a turn-based action that does not use the stack. Once the defending player has made their blocking declarations, priority passes and each player has the chance to cast spells, activate abilities, etc.
2. What happens if a blocking creature is removed from combat after blockers are declared?
If a blocking creature is removed from combat or stops blocking, it’s removed from the damage assignment order and the relative order among the remaining blockers is unchanged.
3. Who gets priority after blockers are declared?
After blockers are declared, the active player (the player whose turn it is) receives priority first. Then, after that player passes priority the next player (the defending player) has priority, and so on.
4. Can I tap a creature after it has been declared as a blocker?
Yes. Once a creature has been declared as a blocker, it is blocked. You can then do anything you could normally do as an instant, including using an ability that requires tapping the creature. The creature is still blocked and combat will proceed as normal between the attacker and blocker.
5. Does declaring blockers use the stack?
No, declaring blockers is a turn-based action and does not use the stack.
6. How do I “undo” a block?
You cannot “undo” a block once it has been declared. The defender cannot go back on their choices once blockers are declared. After blockers are declared, you may have priority to cast a spell, activate an ability, etc. This can allow you to remove or otherwise change the outcome of a declared block by destroying the blocker or removing the attacker etc.
7. Can I cast “Berserk” or similar spells after blockers are declared?
Yes. The declare blockers step is immediately before the combat damage step, meaning it is a legal time to cast spells like “Berserk” or any other instant.
8. Can I play a sorcery after blockers are declared?
Yes. The combat phase has several steps. After blockers are declared, and before the combat damage step, all players receive priority, and can play spells and abilities as normal. This can include casting a sorcery if the game state otherwise allows for it.
9. What is the rule 509 in Magic: The Gathering?
Rule 509 of the comprehensive rules governs the process of declaring blockers. It details how the defending player chooses blockers, how blocking works, and how the attacking player assigns damage to blockers.
10. Who gets to order blockers for damage assignment?
The attacking player decides the order in which damage will be assigned to the creatures blocking each of their attacking creatures.
11. Who chooses blockers?
The defending player chooses which of their creatures will block which attacking creatures.
12. What does “blocker priority” mean?
In the context of Magic: The Gathering, there is no concept of “blocker priority” as in a system that has a list of tasks to be completed in order. In the context of the game itself, this question alludes to the priority all players are granted after the blocking declaration is complete. When referring to a project or other organizational context, “blocker priority” indicates a task that must be completed before other tasks can proceed.
13. What is the main purpose of blocking?
The primary purpose of blocking is to prevent or mitigate damage to the defending player or their planeswalkers. It can also be used to eliminate attacking creatures by assigning lethal damage to them with the blockers.
14. Can you activate abilities after declaring blockers?
Yes. Players can activate abilities after blockers have been declared, but before combat damage is dealt. These actions can be used to modify combat outcomes.
15. Can you cast an instant before blockers are declared?
Yes, you can cast an instant spell any time you have priority, including after attackers are declared but before blockers are declared.
Understanding the intricacies of declaring blockers is crucial for success in card games like Magic: The Gathering. By carefully considering your options, you can make informed decisions that will turn the tide of combat and lead you to victory.
