Yes, absolutely! In Magic: The Gathering, you can cast instants after blockers are declared. This is a crucial aspect of the game that allows for dynamic plays and strategic decision-making. The combat phase is broken down into several steps, and players receive priority in each step, including the Declare Blockers step. Understanding when and how to utilize instants in response to blockers is key to becoming a skilled Magic player.

Understanding the Combat Phase

The combat phase isn’t just one big chunk of attacking and blocking. It’s a series of structured steps, each offering opportunities to react. Here’s a quick rundown:

Beginning of Combat Step: This is the very start. Abilities that trigger “at the beginning of combat” trigger here. Players can also cast instants or activate abilities.
Declare Attackers Step: The attacking player chooses which creatures will attack.
Declare Blockers Step: The defending player chooses which creatures will block. This is the moment we’re focusing on.
Combat Damage Step: Creatures deal combat damage to each other.
End of Combat Step: The combat phase concludes.

Priority and the Declare Blockers Step

After blockers are declared, but before combat damage is dealt, both players receive priority. This means they have the opportunity to cast instants, activate abilities, or take other actions. The active player (the one whose turn it is) has priority first. After they pass priority, the non-active player (the one being attacked) has priority.

Strategic Implications of Instant Speed

This timing is vital because it allows you to respond to your opponent’s blocking decisions. Imagine this scenario:

You attack with a powerful creature.
Your opponent blocks with a smaller creature.
Before damage is dealt, you cast an instant that gives your creature +3/+3.

Suddenly, that smaller blocker is going to have a very bad day. This can completely swing the combat in your favor. You can also use instants defensively, such as casting a spell to protect your own creature from being destroyed by a blocker.

Examples of Instant Use

Here are some examples of instants you might cast after blockers are declared:

Pump Spells: Spells that increase a creature’s power and/or toughness (e.g., Giant Growth).
Removal Spells: Spells that destroy or exile a creature (e.g., Murder).
Protection Spells: Spells that give a creature hexproof or indestructible (e.g., Gods Willing).
Combat Tricks: Spells that affect combat in unexpected ways (e.g., Feign Death).

Frequently Asked Questions (FAQs)

Here are 15 frequently asked questions about casting instants in response to blockers, providing further clarity and helpful tips:

Can I cast an instant to remove a blocker after it has been declared? Yes, you can. If you destroy a blocker with an instant after it has been declared, the attacking creature it was blocking will remain blocked but will not deal damage to anything unless another creature starts blocking it.
If I pump my attacking creature after blockers are declared, does the blocker’s damage stay the same? Yes, the blocker will deal damage based on its power at the time of the combat damage step. Pumping the attacking creature won’t change the blocker’s damage output.
What happens if I cast an instant that makes my creature unblockable after blockers have been declared? It’s too late. Unblockability only matters at the point when blockers are being declared. Once a creature is blocked, it remains blocked for the rest of combat, regardless of any subsequent unblockable effects. Being unblockable only does something when blockers are being declared. If unblockability is granted after this point, it doesn’t do anything.
Can I cast a sorcery after blockers are declared? No. Sorceries can only be cast during your main phase when the stack is empty and you have priority. You cannot cast them during the combat phase.
If my creature has Deathtouch, is it better to wait to cast pump spells until after blockers are declared? It depends on the situation. If you want to ensure your creature survives combat, pumping it after blockers are declared can be a good idea. However, if you want to bluff your opponent into not blocking, you might cast the pump spell before blockers are declared.
If a blocker has First Strike, when do I get to cast instants relative to its damage? First Strike creates a separate combat damage step. After First Strike damage is dealt, players receive priority before the regular combat damage step. This gives you a chance to react to the results of the First Strike damage.
If I attack with two creatures, and my opponent blocks both, can I cast different instants targeting each of my creatures? Yes! Each creature is considered separately. After blockers are declared, you can cast different instants targeting each of your attacking creatures.
Can I cast an instant in response to my own pump spell? Yes! You can respond to your own spells, but you need to explicitly state that you are holding priority after casting the first spell.
If a blocker phases out after being declared, what happens? If a blocker phases out after it is declared, the creature will continue to be blocked, but not deal damage.
Does Deathtouch affect creatures with First Strike if they deal damage to each other at the same time? Not exactly at the same time. In the first combat damage step, the first strike creature deals damage. If that damage is enough to kill the creature with deathtouch, the creature with deathtouch won’t deal damage back.
Can I activate an ability after blockers are declared? Absolutely! Any activated ability that you could normally activate at instant speed can be used after blockers are declared.
What’s the best way to practice using instants effectively in combat? Play lots of games! Pay attention to how your opponents use instants, and try to anticipate their plays. Experiment with different combinations of instants and creatures to find what works best for you.
How important is it to verbally confirm with my opponent that they are done declaring blockers before I cast any instants? Very important. It prevents misunderstandings and ensures a clean game. Always ask, “Are you done declaring blockers?” before proceeding.
If my opponent has a creature with Indestructible, is it still worth casting a pump spell on my attacking creature after it’s blocked? It depends. If you have another way to get rid of the indestructible creature (e.g., a spell that removes indestructible), pumping your creature could be worthwhile. Otherwise, it might be better to save your instant for a different situation.
Where can I learn more about the nuances of Magic: The Gathering rules? There are many great resources online, including the official Magic: The Gathering website and various community forums. Additionally, resources like the Games Learning Society at GamesLearningSociety.org offer valuable insights into the educational and strategic aspects of gaming.

Conclusion

Mastering the timing of instants in the combat phase is essential for success in Magic: The Gathering. By understanding the structure of the combat phase and the concept of priority, you can make informed decisions and outplay your opponents. Remember to always confirm with your opponent that they are done declaring blockers before you cast any instants, and practice using instants strategically to maximize their impact. Good luck, and have fun dueling!
