there are 3 types of card texts that impact the cards

(Passives) are in brackets and can be used once per turn, with no limit on the number that can be used.

_Abilities_ are underlined, and only one on a card can be used per turn

Notes have no modifying characteristics and are used to denote what can and can't be done

E.g.: if you use an ability, you cannot use the other ability/abilities on this card until it leaves and re-enters play

Here's a card that uses all 3 text types:

as you can see, while the passive is not an ability, you still cannot use it on the same turn as throw spear, which is an ability. This means that the damage increase can be blocked by guardira (see below) but the base attack cannot. (I use gray as the image base for cards with white details)
