Hey guys I main tryndamere,And this a champion that you can climb elo by
You can carry the game by him,and he is a very good split pusher,And he does freaking high damage in no time( you can take a turret alone in 10 seconds)
You can play tryndamere as a jungler but I would prefer to play top to carry the game

Tryndamere is a very good champion to carry the game

He is a very good and fast split pusher
Try to farm as much as you can
You can use your E to run through walls
You can restore to full health in no time
You can use your E to dodge a lot of skills

You can slow your enemy with your basic attack which is the main damage
You deal a lot of damage when you are low health which is useful in your ult
You get early boots which is important in early game
You can use the minion item to kill the canon minion so that you can 1 hit the canon minion in late game

In team fights,Use your E to roll in and activate your ult and try to target the marksman,And when the ult is about to end get out with your E and then use Q to get some health back,And by this way you did a lot of damage and you are still alive

Try to max your Q first because It is the source of damage when you have fury,then max your E,and at last max your W

You need the teleport to go to a spot faster,and tryndamere is high damage champion so you can get a turret in 10 seconds using your teleport

Try to farm as much as you can,And remember farming is more important than killing,You can get full build and full lvl in 30 mins

Pros:

Tryndamere can carry the game
Tryndamere can get easy fast farm
He is the king of split pushing
He can recover full health in no time

Cons:

He is not very good in team fights but he can do some damage like I said in the"Team Work" Chapter
He can get countered by marksman easily so you have to be careful
