Reaction
Reactions are an uncommon stat found on a handful of cards. They serve as alternative ways for these cards to trigger besides their 
Counter reaching 0. In many cases, cards with Reactions don't even have Counters at all, and thus can only trigger via the Reaction.
Information and Strategy
Reactions are found on both player and enemy cards. Unlike the usual Counters, a card with a Reaction will trigger immediately whenever some condition is met. When a card reacts, it triggers basically identically to any card that triggered via its Counter; the card will trigger against the front enemy in the row (unless it also has Barrage, Aimless, or Longshot, in which case it follows the targeting of the ability), and if the card has 
Frenzy then it will trigger multiple times. The most common Reaction is the Smackback keyword, which causes the card to trigger against any card on the field that hits it. Notably, if a card's Reaction causes it to trigger against a specific target, such as Kobonker or a card with Smackback, it will stop attacking if the target is killed in the middle of Frenzy attacks. However, if this sort of card also has Barrage, Aimless, or Longshot, it no longer triggers specifically against its target. It will attempt to trigger against the intended target, but it will also abide by its ability's targeting; for instance, a card with Barrage and Smackback will react against the entire row that its attacker occupies. Any card that has one of these abilities can use all its Frenzy in one reaction, even if the intended target is killed partway through the attack.
Although Smackback is the most common Reaction, it is far from the only one. All Reactions are written in orange ability text to indicate what triggers the Reaction, while any other abilities the card may have are colored normally. For instance, Mega Mimik has the orange text "Trigger when an ally in the row attacks," indicating its trigger condition, and "Lose 1 
Scrap" in normal text, indicating that this is an ability unrelated to what causes the Reaction.
As long as a card is inflicted with 
Snow, any Reactions it has will stop working. Even if the Reaction's conditions are met, the card fails to trigger. This includes if the card would react to the hit but the hit inflicts it with Snow; for instance, Snoof attacking a Spike Wall will not trigger the latter's Smackback. Similarly, if a card with a Reaction is inflicted with 
Ink, all its abilities are negated and thus the ability that triggers the Reaction is negated. If the card would react to being hit but the hit inflicts it with Ink, it will not react. For instance, Maw Jaw triggers when hit by anything. Using the Flask of Ink on it counts as a hit (since the Flask of Ink has an 
attack icon), but because it Inks Maw Jaw it cannot react.
Reactions are separate from any non-triggering ability that activates under a specific condition, and those abilities can still activate even if the card is Snowed. For instance, if a card has the 
Punchfist Charm and the 
Tiger Charm attached, it will gain Smackback and "Gain 1 
Teeth when hit." However, if this card is Snowed and thus cannot trigger via Smackback, it will still gain Teeth when hit by something. If this card becomes Inked, both of these abilities are negated, and it will not react when attacked or gain Teeth when hit.
Reactions trigger immediately whenever their conditions are met. This means that counterattack reactions like Smackback will interrupt attackers with Frenzy, reacting before the Frenzy attacks finish (which may even kill the attacker before they finish their attacks). Similarly, Mimik and Mega Mimik trigger in between hits if the attacking ally in the row has Frenzy. If a card's Reaction causes it to trigger against multiple specific enemies at once (such as if Snoffel inflicts the entire enemy field with Snow while Kobonker is on the field), the card will trigger against each appropriate target. If a card with Smackback attacks another card with Smackback, the cards repeatedly attack each other until one or both of them is destroyed. The only game state action that is higher-priority than checking a card's Reaction is checking if the card's 
Overburn should cause it to explode. If a card would react to something that also causes its 
health to be lower than its Overburn (whether by inflicting Overburn or damaging it such that its health is lower than its Overburn), it will explode before it gets the chance to react. If the card survives its own explosion, such as with 
Block, it will react after the explosion.
