Glossary

Quick reference for all game terms, organized alphabetically.

A B C D E F G H I L M O R S T U

A

Ace: supertype A unit supertype that makes a unit eligible to serve as your Ace in Ace Battle format. In other formats, Ace Units function as normal units. Multiple copies allowed in deck, but only one can be on the field at a time.
Ace Battle: format A format where each player chooses an Ace Unit before the game that is always in play and defines their deck's strategy.

B

Bench: zone The zone where a knocked-out Ace goes in Ace Battle format. The Ace can be replayed from the Bench by paying its original energy cost.
Bounce: keyword Blue keyword. Return a target card to its owner's hand.
Budget: system The point allowance a card earns from its energy cost. Formula: 2 × cost + 2. Stats, keywords, and effects must fit within this budget.
Burn X: keyword Red keyword. When this unit attacks and deals damage, deal X damage to the defending player. Does not trigger if the unit is killed before dealing damage (e.g. First Strike), if its Might is reduced to 0, or if all damage is absorbed by Shield.

C

Card Tax: system The inherent cost of spending a card from your hand to play it. The +2 in every budget formula reimburses the player for paying this tax (1 energy = 2 budget). Rewards immediate play over setting cards for later.
Challenge: effect A spell effect that causes two units to fight each other. See Fight.
Conduit: keyword Green keyword. When energized in the Energy Zone, this card counts as 2 energy instead of 1. Both energies must be spent on the same card or effect — they cannot be split.
Counterspell: effect Blue trap — when a spell is played, counter it. Hard counter gated by the set-and-wait trap requirement.
Curse: keyword Black keyword. Equip a debuff to an enemy unit or player. Cursed Items occupy the target's only item slot.

D

Defuse: effect Blue spell — return target set card to its controller's hand. Proactive disruption that resets trap setup timers.
Drain X: keyword Black/Green keyword. Attack only — when this unit attacks and deals damage, gain X life. The life gained is fixed (X), independent of damage dealt. Triggers on every hit.
Draw X: effect Draw X cards. Budget cost: 2 × X (premium — card advantage).

E

Exile: zone A zone for exiled cards. Cards in Exile cannot be recycled back into the library. Blue's surgical mill sends cards here.
Encounter Deck: system A pre-built deck used in PvE and PvPvE modes. Contains boss cards, minions, hazards, scheme/doom cards, and events. Runs automatically by default; optionally player-piloted.
Endurance: stat A unit's defense stat. Damage absorbed before the unit is destroyed. Resets at end of turn.
Endure: keyword Green/Black keyword. The first time this unit would be destroyed by damage each turn, it survives with 1 Endurance and becomes exhausted instead.
Energize: mechanic Place a card face-up from your hand into the Energy Zone. Once per turn. The card enters exhausted (not available until your next turn). Converts the card into a permanent energy source.
Energy: resource The currency spent to play cards. Generated by energized cards in the Energy Zone (permanent, readies each turn) and by discarding hand cards (one-time burst).
Energy Zone: zone The zone where energized cards sit face-up, generating energy each turn. Capped at max hand size (5 in Standard).
Equip X: keyword This unit can hold X items. Vanilla units default to 1 item slot. Budget cost: 0 (free).
Exhaust: keyword Blue keyword. Target unit becomes exhausted and does not ready next turn.
Exhausted: state The spent state of a card. Exhausted cards cannot attack, block, or use activated abilities. Cards ready at the start of their controller's turn.

F

Field Spell: card type A continuous spell in the Field Zone providing an ongoing effect. Requires spell nullification to destroy.
Field Zone: zone A single slot for one persistent field-wide effect. Playing a new field card replaces the existing one.
Fight: mechanic A keyword action. Each unit deals damage equal to its Might to the other. Combat keywords (First Strike, etc.) do not apply. Neither unit changes ready/exhausted state.
First Strike: keyword Universal keyword. This unit deals damage before the defender in combat. If it kills the enemy before they strike back, it takes no damage. Budget cost: max(Might − 1, 0).
First-Player Balance: rule In 1v1, player 2 draws an extra card (hand of 6) and may set 1 card face-down before the game begins. Compensates for player 1's tempo advantage.
Flying: keyword This unit can only be blocked by units with Flying or Reach. Budget cost: ⌊(Might − 1) / 2⌋. No primary color — placed thematically.
Foresight X: keyword Blue keyword. Look at the top X cards of any library; may rearrange.

G

Gravebound: keyword Black keyword. This card always stays in the graveyard when the graveyard is reshuffled into the library. Mandatory downside.
Graveyard: zone A player's discard pile. Cards go here when destroyed, discarded, or used. Can be reshuffled into the library when it's empty (with a penalty).
Guard: keyword White keyword. Forces attackers to target this unit before the player. Budget cost: 1 (flat).

H

Hand Payment: mechanic Discarding cards from hand to pay costs. Each card provides 1 energy of its color as a one-time burst.
Heal X: keyword White keyword. Restore X life to a player or X endurance to a unit.
Hunter: keyword Universal keyword. When this unit attacks, it may target an enemy unit instead of a player. The targeted unit readies (if exhausted) and fights back. Guard units still intercept. Budget cost: max(Might − 2, 2).

I

Items: card type Persistent cards that attach to units (1 per unit by default). Subtypes: Weapons, Armor, Relics/Artifacts, Cursed Items. Destroyed when host unit is destroyed.

O

Overkill: keyword Green primary keyword. When this unit deals combat damage to a blocker, excess damage beyond the blocker's remaining Endurance is dealt to the defending player. Budget cost: max(Might − 2, 0).

R

Reach: keyword Green keyword. This unit can block Flying units. Budget cost: 1 (flat). Purely defensive counter to Flying.

Spells: card type One-time effect cards. Can be played from hand or set face-down for later (your turn only).
Subtypes: system Tribal tags on units (Dragon, Pirate, Dinosaur, Ninja, Vampire, Beast, Insect, etc.) that enable synergy effects. Open-ended — new sets add new subtypes.
Summoning Weakness: rule Core rule (not a keyword): units cannot attack or activate abilities the turn they enter play. Rush allows attacking; it does not bypass the ability restriction.

T

Traps: card type Reactive cards that must be set face-down before activation. Activate at declared trigger windows during any player's turn. Must wait one full turn after setting. Paid on activation, not when set.

U

Units: card type Cards that attack, block, and occupy the field. Have Might/Endurance stats. Can carry the Ace supertype and one or more subtypes.
