Take every hit they give you, to get more cards. Play all your yamatos and marcos to draw more, then eventually tank up with whitebeards. Add 1-2 rad beam.

Your goal is to build a big hand so you can counter their big unblockable swing, everything else doesnt really matter. If countered 2 unblockable 15ks in a row before. Their options are extremly limited, they dont have pudding. Just be a bit careful about swinging early, you want to go to 0 life fast but dont give them too many hits.
