Ball Lightning (Blue)

If a Lightning or Elemental action card would deal damage this combat chain, instead it deals that much damage plus 1.

Go again

Rulings

From the Tales of Aria release notes

This affects all instances of damage including if an Elemental or Lightning action card gained “deal 1 damage”.
Ball Lighting does have a defense value (0 is a value) and can defend. (This is different than if there was no defense value)

Older rulings (1)

Playing a non-attack action closes the combat chain, therefore Ball Lightning’s replacement effect does not apply to non-attack action cards. This does apply non-attack actions that are played as though it was an instant when the combat chain is still open.
Changed 2022-02-11
The combat chain must already be closed to play a non-attack action normally, so Ball Lightning’s effect never applies to one; it still applies to a non-attack action played as an instant while the chain is open.

Keyword notes

Go again - Go again allows multiple actions to be played in a turn when usually playing an action with use up your action point, and therefore end your turn. A card with go again gives the controller of that card or activated ability 1 action point when it resolves.

When an action with go again resolves, its controller gains 1 action point.
Multiple instances of go again on the same card or activated ability do not stack. If a card or activated ability has multiple instances of go again when it resolves its controller gains 1 action point only.
If an action with go again does not resolve, its controller does not gain 1 action point.
You cannot reveal a card with no to Belittle. The card must have a value to its power that is 3 or less. (0 is a value)
