How can I beat this guy? I can't train with Mikhail anymore. What Should I do? Or I need to plan how to use my energy in fight?
You should train with Mikhail twice
and train in the college gym with the Dean and Vera several times to gain three additional strength points (new in the current version) so you're almost as strong as the dude. Being more aggressive than in the previous fight is helpful, understanding the details of the fighting game too - but you should be able to make it in a few tries if you're strong enough. Just make sure to select a good deck of cards! I recommend three attack cards with
one (not two!) lightning each, one defend card with
two block and one piledriver.
