Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Best part about this team, NO DEATHS!!!
Just run in blow the other team up for 2k hits. Since you'll have 125% lifesteal, you shouldn't be losing hp at all unless they disable you. At that point though, the undying rage will keep you up for long enough to get to them and lifesteal to full.
Sure that's when you're winning, but what if you're losing in kill? No prob. Just one of the Tryndameres should be strong enough to BD the whole base while 4 sit on D.
