What is a spell?
Card types:
- Sorcery, Instant – do things
- Artifact, Creature, Enchantment, Planeswalker – become things
- Land – a land is never a spell
- Other stuff – Archenemy Schemes, Planechase Planes, etc., not spells
Two important action words: “Cast” and “Play”.
Not an ability, though largely similar in procedure, and uses most of the same rules (Examples: Reinforce, Forecast, Faerie Macabre).
Fine distinctions between abilities that let you cast a spell (Flashback, Retrace, etc.) and those that don’t (Unearth, Ninjutsu) – critical component is rules for the ability.
Copy of a card can also be cast.
Brief overview of previous rules
- Interrupt window
- “Successfully cast”
- Rules of casting a spell
Illegal actions cause the entire process to be reversed.
Steps to casting a spell
A popular mnemonic to aid in remembering the order of these steps is All Crazy Teens Have Tried Magic Pills.
1. All = Announce (601.2a)
Verbal announcement
Move card (or copy) to the stack
Casting a face-down spell (not explicit in 601.1):
The card is put on the stack face-down
Legality of casting is determined by the face-down characteristics (examples: Gaddock Teeg, Crucible of Worlds)
2. Crazy = Choices (601.2b)
How to cast
Modes (emdash, “Choose one” or similar)
Splice (choose and reveal)
How to pay
Additional/alternative costs (announce intent)
Value of X (when applicable)
Hybrid/Phyrexian mana
3. Teens = Targets (601.2c)
Announce number of targets (if variable)
Must choose a legal target for every target required
Targeting restriction – phrase describing the target that appears in immediate proximity to the word “target.” (Red Elemental Blast)
Not a targeting restriction – conditional phrases (Pyroblast)
Choosing the same target multiple times depends on whether there are multiple instances of the word “target.” (Hex vs. Seeds of Strength)
4. Have = How to Divide (601.2d)
Each target must receive at least one of what’s divided.
This requirement applies only where the player divides (Arc Lightning), and not otherwise (Fireball).
5. Tried = Total Cost Determination (601.2e)
Total cost includes all costs, not just mana.
Mana – most common cost
Start with mana cost or alternative cost
Add cost increases
Subtract cost decreases
Apply cost-setting effects (Trinisphere)
Additional costs
Cost is now “locked in” and cannot later be changed.
6. Magic = Mana Abilities (601.2f)
Specific window to activate mana abilities when the player does not have priority
Window opens only where the total cost includes a mana payment
Mana abilities resolve immediately without using the stack
Note special timing restrictions on some mana abilities (Example: Lion’s Eye Diamond, Rhystic Cave)
7. Pills = Pay (601.2g)
Costs can be paid in any order
All costs must be paid, or the spell was illegally cast
Null cost can’t be paid (Evermind)
Opponents choosing (601.3)
If a spell calls for an opponent to make a choice (Example: Evangelize) you choose which opponent makes the choice, and he or she chooses when you would normally choose.
Example scenarios
- Announce Fiery Justice and put it on top of the stack.
- No choices to be made.
- Select targets. Variable number of target creatures or players. Targeting an opponent for the last clause is mandatory.
- Divide damage among the targets. Each target creature or player must be assigned at least 1 damage.
- Cost is simply the mana cost.
- Activate mana abilities
- Pay the cost.
- Announce Cryptic Command and put it on top of the stack.
- Choose modes.
- Select targets, if applicable. Number of targets will depend on the modes chosen.
- No division.
- Cost is simply the mana cost.
- Activate mana abilities.
- Pay the cost.
- Sacrificing Sphere of Resistance to Shrapnel Blast
- Announce Shrapnel Blast and put it on top of the stack.
- No choices to be made.
- Select target.
- No division.
- Cost is the mana cost, plus an additional cost of 1 from the Sphere, plus an additional cost of sacrificing an artifact.
- Activate mana abilities.
- Pay the costs.
- Announce Chord of Calling and put it on top of the stack.
- Choose to pay convoke costs.
- No target to be selected.
- No division.
- Cost is the mana cost, reduced appropriately by convoke, plus the additional cost of tapping creatures.
- Activate mana abilities (such as sacrificing the Wild Cantor.)
- Pay the costs.
Conclusion
Exact steps are necessary to know details of what’s legal and what’s not.
