That looks correct to me.
Removing cascade basically means "unplaying" a card doesn't negate that card.
Negate a band ability, and the abilities of the characters banded in remain unless they turn themselves off (Cloud Moses only negates cards in battle while he's in battle).
Negate an add to battle ability, and the abilities of the cards added to battle remain unless they turn themselves off.
Negate an activate an Artifact ability, and the abilities of the activated Artifacts remain unless they turn themselves off.
