How do you tell when something is an ongoing ability, and when it is just an instant ability?
For example:
Jaddua, Son of Jonathon S/A: If Zerubbabel's Temple is in play, Negate all special abilities on Curses. Protect all Artifacts in play, hand, and artifact piles from discard.
If I bring him in battle, does he negate curses and protect arts for the rest of the game? or only during the battle phase?
