Yes, cast triggers do happen even if the spell that triggered them is subsequently countered. The key lies in understanding how the stack works in Magic: The Gathering. When you cast a spell, its “when cast” triggered abilities immediately go on the stack on top of the spell itself. Only after these triggers are on the stack can an opponent respond with a counterspell. Countering the original spell only removes that spell from the stack; the triggered ability remains and will resolve as normal. It’s a crucial distinction that separates “cast” triggers from “enters the battlefield” triggers.
Understanding the Stack and Timing
The stack is the game’s memory center. Everything that happens in a game of Magic goes on the stack, waiting to resolve. Spells, abilities, and even triggered abilities all take their place in line, resolving one by one until the stack is empty.
The important thing to remember about cast triggers is that they trigger immediately upon casting the spell. This means they hit the stack before your opponent has the chance to react with a counterspell. By the time they can say “I counter that!”, the triggered ability is already in line, patiently awaiting its turn to resolve.
Why “Cast” Matters
The phrase “when you cast” is crucial. It signifies that the trigger happens as part of the process of casting the spell, not as a result of the spell resolving or entering the battlefield. This distinction is critical, setting these abilities apart from other types of triggers in the game.
Example Time!
Imagine you cast a spell called “Explosive Genesis” that has the following text: “When you cast Explosive Genesis, create three 1/1 green Saproling creature tokens.” Your opponent, desperate to stop your growing army, casts Counterspell, targeting Explosive Genesis. What happens?
- You cast Explosive Genesis, putting it on the stack.
- The “when you cast” ability triggers and goes on the stack above Explosive Genesis.
- Your opponent casts Counterspell, targeting Explosive Genesis. It goes on the stack above the Explosive Genesis trigger.
- Counterspell resolves, removing Explosive Genesis from the stack and sending it to the graveyard.
- The Explosive Genesis trigger resolves, creating three 1/1 Saproling tokens.
Despite the counterspell, you still get your tokens! This exemplifies how cast triggers function independently of the spell that triggered them.
FAQs: Delving Deeper into Cast Triggers
Here are some frequently asked questions to further clarify the nuances of cast triggers and their interactions with other game mechanics:
1. Does countering a spell mean it wasn’t cast?
No, a spell that’s countered was cast. The act of casting happens when the spell moves from your hand to the stack. However, because it was countered, it never resolves and its effects are negated.
2. Does a countered spell trigger Prowess?
Yes, a countered spell does trigger Prowess. Prowess triggers when you cast a noncreature spell. Even if that spell is countered, the Prowess ability has already triggered and will resolve, giving the creature +1/+1 until end of turn.
3. Does Cascade still trigger if the original spell is countered?
Yes, Cascade is a triggered ability that activates when you cast the spell with cascade. Countering the original spell doesn’t stop the cascade ability from resolving.
4. Does copying a spell trigger cast triggers?
No, generally, copying a spell does not trigger cast triggers. Copies are put directly onto the stack; they aren’t cast. There are very specific exceptions if the card says otherwise.
5. Can you cast an instant in response to a triggered ability?
Yes, you absolutely can cast an instant in response to a triggered ability. Triggered abilities go on the stack, and players have the opportunity to respond to anything on the stack with instants and activated abilities they control.
6. Does Flashback count as casting a spell?
Yes, Flashback does count as casting a spell. You’re paying an alternative cost to cast the spell from your graveyard, but it still goes through the normal casting process.
7. Do countered spells count towards Storm?
Yes, countered spells do count towards the Storm count. Storm counts the number of spells cast in a turn, regardless of whether those spells resolved or were countered.
8. Can you counterspell a contingent spell?
No. The Contingency card allows you to cast another spell when you cast it, and makes it “take effect” when a condition is met. The second spell is already cast at this point, so the condition does not allow for a counterspell.
9. What is rule 112.1 in Magic?
Rule 112.1 defines what a spell is. It states: “A spell is a card on the stack. As the first step of being cast (see rule 601, “Casting Spells”), the card becomes a spell and is moved to the top of the stack from the zone it was in, which is usually its owner’s hand.”
10. Does Maelstrom Nexus count itself?
Maelstrom Nexus checks to see if spells were cast. The card doesn’t trigger itself.
11. Does a triggered ability target the caster of the countered spell?
No, a triggered ability does not typically target the caster of the countered spell. Triggered abilities can target players, permanents, spells, or other things, depending on the specific wording of the ability. The target is determined by the ability’s text, not the fact that the spell was countered.
12. Can Deflecting Swat make a Counterspell counter itself?
No, you cannot make a Counterspell target itself. A spell cannot target itself. However, you can use Deflecting Swat to redirect the Counterspell to target Deflecting Swat itself.
13. Does Rule 704.5 affect cast triggers?
Rule 704.5 describes State-Based Actions. This rule does not affect cast triggers, which are triggered when spells are cast, independent of State-Based Actions
14. Is there a delay to cast instants?
No, there is no delay for the actions in a spell to occur.
15. Does Rule 603.6 apply to cast triggers?
No, Rule 603.6 applies to “leaves-the-battlefield” abilities. Cast triggers are not “leaves-the-battlefield” abilities.
The Strategic Implications
Understanding the interplay between cast triggers and counterspells is crucial for strategic gameplay. It influences deck building and in-game decision-making. Knowing that your “when cast” triggers will resolve even if your spell gets countered can significantly impact your choices. You might be more willing to cast a powerful spell with a valuable trigger, even against an opponent with open mana, knowing you’ll still get some benefit.
Conversely, if you’re playing against a deck with numerous “when cast” triggers, you may need to adjust your counterspell strategy. Holding counterspells for creatures and other spells is generally better, so your opponent doesn’t get any benefit from the triggered ability of a countered spell.
