Shen although portrayed as a ninja is a tank, or a bruiser if needed. his kit is very versatile as a top laner and a support this build will be focused on top lane Shen. His Q is a consistent empowered auto that does percentage health damage, his w adds to his tankiness and can win team fights by itself if placed right to protect your teammates, his e is a dash as well as a taunt, his r is a global save your teammate button. although Shen is sorta out of meta for top laners, he is still a viable choice if used by a skilled player

I'm going to be frank, Shen in lane can be a nightmare, odds are you'll lose lane 2 out of 3 times. He can surprised opponents by how much damage his q can do in lower levels so if people want to trade early on DO IT! then dash back behind your minions, if you taunt them in the process that's great! During laning just focus on last hitting, don't try to push in too far, if you are in the middle of the lane at a stale mate try not to use your e too much as it is your only escape. try not to worry about getting a solo kill, wait for a gank or till you are level 6.

Hopefully you haven't lost lane yet, your ult gives your team such a huge global pressure. have a constant eye on the map to see if you need to save a teammate or to turn a fight. try to let your carries get the kills but if you take one oh well. just remember you may lose lane but you'll help win other peoples lane which'll pay off late game

team fights are for the most part pretty simple, if your team has at least carry who know how to do their job, just do you're e q w combo on their adc or other auto attack based carry. if you go the bruiser build you can still do this but be careful as you are not full tank. your ult is a very helpful way for you to join in a team fight while you're out farming some other lane

only way to win this is to SPLIT PUSHHHHHH, if you go tank use your banner to empower minions, and if you go bruiser you can handle 1 on 1 duels maybe 1v2 if you yourself are ahead.
