No, a creature with 0 toughness cannot block in Magic: The Gathering. The reason is simple: state-based actions. These actions are a fundamental part of the game that are checked before any player receives priority to take actions like declaring blockers. If a creature’s toughness is 0 or less, it is immediately put into its owner’s graveyard as a state-based action before the declare blockers step. Therefore, it won’t even be around to be declared as a blocker in the first place.
Understanding Toughness and State-Based Actions
Toughness, represented by the number after the slash on a creature card (e.g., 2/2 indicates 2 power and 2 toughness), signifies the amount of damage a creature can sustain before being destroyed. When a creature takes damage equal to or greater than its toughness, it is normally destroyed. However, having 0 or less toughness is a special condition. It triggers a state-based action that bypasses combat damage entirely.
State-based actions are automatic game processes that check for certain conditions and enforce rules immediately. One such rule is the “toughness 0 or less” rule. The game checks for these actions before any player has the opportunity to cast spells or activate abilities during the declare blockers step, guaranteeing that the 0 toughness creature is already gone.
Examples and Implications
Imagine you have a creature that normally has 1 toughness, but your opponent casts a spell reducing its toughness by 1. It becomes a 0/X creature. Before you can declare blockers, the game checks state-based actions. Seeing a creature with 0 toughness, it’s immediately sent to the graveyard. Therefore, this creature can never be declared as a blocker.
This rule applies to tokens as well. If a token creature somehow ends up with 0 toughness, it disappears immediately due to state-based actions. Token creatures that go to the graveyard cease to exist.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about creature toughness and related rules in Magic: The Gathering:
1. What happens when a creature has 0 toughness?
When a creature has 0 or less toughness, it is immediately put into its owner’s graveyard as a state-based action. This happens before any player receives priority to take actions.
2. Is a creature with 0 toughness sacrificed?
No, a creature with 0 toughness isn’t sacrificed. Sacrifice is an action a player takes, often as a cost to activate an ability or as part of a spell’s effect. A creature with 0 toughness dies due to state-based actions, which are automatic game processes, not player actions.
3. Can a 0/0 creature block?
No, a 0/0 creature cannot block. The game checks for state-based actions before any player gets priority, meaning the creature will be in the graveyard before it has the chance to block.
4. Can you block with a 0/0 token?
No, you cannot. Similar to a regular 0/0 creature, a 0/0 token is immediately removed from the battlefield and ceases to exist due to state-based actions.
5. Does Deathtouch cancel Deathtouch?
The article mentions “Any two instances of the Deathtouch ability against one another cancel out the Deathtouch ability.” This statement is incorrect. Deathtouch works independently. If two creatures with Deathtouch deal combat damage to each other, both creatures are destroyed. Multiple instances of Deathtouch on a single creature do not cancel each other out; one instance is sufficient.
6. Does Deathtouch beat indestructible?
No, Deathtouch does not overcome Indestructible. Indestructible means a permanent cannot be destroyed by damage or “destroy” effects. While a creature with Deathtouch dealing damage would normally destroy a creature, Indestructible prevents this destruction.
7. Is 0 considered even in MTG?
Yes, in Magic: The Gathering, 0 is considered an even number. This is relevant for certain card abilities that trigger based on even or odd numbers.
8. Can you deal 0 damage in MTG?
While a source can be prevented from dealing damage, the act of dealing “0 damage” is technically not dealing damage at all. If a source would deal 0 damage, it deals no damage at all. Abilities that trigger when damage is dealt will not trigger if the amount of damage dealt is zero.
9. Can you regenerate a creature with 0 toughness?
No, you cannot. The rules specifically state that regeneration cannot replace the event of a creature with 0 or less toughness being put into the graveyard. Regeneration replaces destruction, but the game handles 0 toughness creatures automatically through state-based actions.
10. Can you exile indestructible?
Yes, you can exile an indestructible permanent. Indestructible only prevents destruction; it doesn’t protect against being exiled, bounced (returned to hand), or sacrificed.
11. Can you sacrifice a 0/0?
No. The State-Based Actions are checked, and the 0/0 dies, before you get priority to activate any ability.
12. Does indestructible prevent sacrifice?
No, Indestructible does not prevent sacrifice. Sacrifice is not destruction; it is a player taking an action to move a permanent from the battlefield to its owner’s graveyard as a cost or effect.
13. Can a spell cost 0 in Magic The Gathering?
Yes, a spell can have a mana cost of {0}. However, even though it doesn’t require mana, it still needs to be cast like any other spell.
14. Can you discard a hand of 0 MTG?
Yes, you can discard an empty hand. This is relevant for cards that require you to discard your hand and then draw new cards.
15. Does First Strike avoid Deathtouch?
Yes, First Strike can negate the effects of Deathtouch. If a creature with First Strike deals lethal damage to a creature with Deathtouch during the first combat damage step, the Deathtouch creature is destroyed before it has a chance to deal damage back.
Understanding Rule 0
The article mentions “Rule 0” which is the social contract of Magic: The Gathering. It allows players to adjust or modify the rules of the game for their playgroup, but it should always be done with the agreement of all participants.
