Sorry, Attacks, not moves
Anyway, this Inferno Gust card is a good example of an attack
At the top left, you see a 1. This is how many build points Inferno Gust costs. Your attack deck must have exactly 20 attacks and 20 buildpoints. You have 3 attacks in your hand, and draw a new one whenever you use one.
Looking at the meat of the card, you see a large 0, a 5 under the fire column, and a 5 under the water column.
The big 0 represents how much damage it does base: 0
the 5 under the air and fire columns show how much damage the attack does if the attacker has the fire and/or air elements.
Below that, we see "Chalenge: speed 15." This is a clause that only activates if the attacker has 15 more speed than whomever he's attacking
If, for example, Rarran attacked Nauthilax with Inferno Gust, he would do 15 damage: 5 because he has Air, and 10 because he has more speed.
