This build is a perfect example of tryndamere's skills. Since his passive gives him a total of 35% critical chance at 100 rage, I built him to maximize his critical damage with ~285% critical damage which is a lot of damage and with this build he has ~90% critical chance so critical hits are more than 9 hits on 10! He deals damage around 900-1200 depending on enemy armor and since he has frozen mallet, atma's impaler and maw of malmortius makes him a good combo. For example; Tryndamere's bloodlust's passive gives him 0.5 attack damage for each 1% health missing in combination with maw of malmortius he has 2.0 attack damage with every 1% health missing and that is a good combo with undying rage because he last 5 second with 1 hp! so he gets over ~100 more attack damage
