Is a card's ability limited to once per turn, and does that apply to whenever or ongoing abilities?

Question

Accepted Answer

Yes for abilities you activate with a worker: each one can be activated once per turn. A 'whenever' ability is not activated, so it triggers each time its condition happens. An ongoing ability stays in effect until its card or worker is refreshed.
