Q: Can I use a Surprise from my set-aside hand to cancel a Surprise played on one of my Draw 2 & Use Em, or Draw 3, Play 2 Actions?

Also, could I use a Surprise that was part of the subturn to cancel the attacking Surprise, and if so would that count as one of the plays?

Example:
Player #1 plays “Draw 3, Play 2 Of Them” and gets an Action, a Keeper, and a Surprise.
They play their Action and Player #2 plays Belay That [Avast, Stop That] to cancel it.
–> can Player #1 use the Surprise in their mini-hand to cancel that Surprise,
–> and if so do they still get to play their Keeper afterwards?

A: Yes, you can use a Surprise from your main hand, or from your sub-hand, to cancel another player’s Surprise during your Draw 3, Play 2 Action. Playing a Surprise to cancel a Surprise is a free action, so yes, you would get to play the third card if your second card is a Surprise that you use to counter a Surprise being used to stop your first card.
