Can Vi's ability be activated multiple times without a flip/exhaust cost, and is recycling a card from trash mandatory?

Ruling: Vi's ability is an activated ability that can be used as many times as you want on your turn, but you must pay the cost (recycle a card from trash) each time you use it.

Nuances:

• The ability can only be used on your turn, not on opponents' turns
• Must be done before showdowns
• Vi needs to survive/hit for the bonus to matter
• Works well in Jinx decks with discard synergy but can be countered by stuns, hidden blades, smoke screens, and other removal
• Vi only recycles cards from your own trash
