The build I used made it very easy. I had 13 stamina to start the fights, all from gear. If you have that much stamina, then I recommend the following:
5 x Nimble+
2 x Body Slam+
4 x Harness+
5 x Boobs Strike+
Spend your first round cycling through to get as many Nimble+ activated, then you can spend the next round looping through the small deck, increasing your armor and doing damage based off it.
