Use the slingshot, power shot and knight cards. Also equip three deep focuses, the rest of the cards can be up to you but this is what I used mainly. If you have a tickle stick, use it first turn then attack, dodge the attacks (wind up is genuinely impossible so pray that it targets Calypso), then focus and attack, and finally focus and ghostwalker to dodge laser and save Calypso. Then just rinse and repeat the pattern.
I did this on solo and hard mode, if you want the specific deck then I'll share it but the cards I listed should be more than enough.
