Can I use Gust at reaction speed to bounce Vi back to hand while my opponent is pumping her up, and is Vi's recycle ability resolved one activation at a time?

Ruling: Yes, you can use Gust at reaction speed to bounce Vi back to hand as your opponent starts using her ability (when she reaches 3 power). Vi's recycle ability is resolved one activation at a time, not all at once.

Sequence:

• Vi's ability activation goes on the chain
• Each use of Vi's ability is processed 1 by 1
• You cannot wait for them to recycle all cards then respond with Gust

Nuances:

• Gust can only target Units at a battlefield
• Vi's ability can only be activated during an open neutral state in the action phase
• Vi cannot activate her ability while contesting/in combat
