Keyword Reference
Keywords are short words in brackets that stand for a whole rule, and the small reminder text on the card says what each one does. This is the reference: every keyword on the site, with its rule and a card that shows it. Most have a one-move drill, in this order. You don't have to do them all at once. The questions at the end check the combat ones.
Timing and how a card is played
- [Accelerate]: Pay 1 Energy and 1 Power of the unit's Domain more as you play it, and it enters ready. (Its drill is in the Gear and [Equip] lesson.)
- [Action]: You can play this on your turn or during a Showdown, not only on a quiet turn.
- [Ambush]: You may play this unit as a Reaction to a battlefield where you already have units.
- [Deploy]: This gear is played to a battlefield (any one, even an enemy's), never to your base. It stays there and is killed when an opponent holds that battlefield.
- [Flow]: You may play this spell from your trash for its Flow cost; then it's removed from the game.
- [Hidden]: Hide it face down for 1 Power; from the next turn on you may play it for free as a Reaction. (No drill: you practise it in the Hidden lesson of Chapter 6.)
- [Legion]: You get the bonus effect if you've already played another card this turn.
- [Quick-Draw]: This gear has Reaction, and when you play it, it attaches to a unit you control.
- [Reaction]: You may play this any time, even before earlier spells and abilities resolve. (No drill: you practise it in the Reaction lessons of Chapter 6.)
- [Repeat]: Pay the extra cost to do the spell's effect a second time.
- [Show Off]: As you play it, you may reveal a fitting card from your hand or pick one on the board, for a bonus. (Its drill is in the Show Off lesson.)

Which keyword makes a unit take combat damage first?
Your Mutated Mouser ([Tank], 1 Might) and Shipyard Skulker (3) attack Darius's Eager Drakehound (3 Might). The Drakehound's 3 damage has to go somewhere. Who survives?
Make your guess, then play the drill to find out.
Signature cards are cards tied to one champion: Annie's Tibbers, for example. You may only put one in your deck if it matches your own Legend, and you can have at most 3 Signature cards in total. They're not Champion units, so one can't be your Chosen Champion.
