Thresh in the top lane is a battle of wits, confuse your apponents with your supprising burst and sustain while also having amazing gank synergy with engage junglers.

League of legends is full of mobile champs, maybe even Too full, thresh does not care, he reaps all. Put the fear of god into the dash combo champs like irelia, urgot, camille and Vi. Thresh can cancel almost every dash in the game, so try it out!

A large amount of top laners are melee stat checking juggernaughts, keep your distance and respect their damage output, get the cs you can and try to freeze at your tower (keep enemy wave at a 4 caster minion advantage always), and remember, in most 1v1 tower dives thresh has the advantage and can even pull champs under tower, if the enemy steps too far up, use this combo (practice in practice tool of course) q into r into q2 into e auto auto and if you win the trade great but hopefully you killed them.

Ranged top laners are usually a menace of the entire lane, but not for thresh! Champs like lillia and urgot are easily out ranged by thresh, but make sure to run doran's shield and second wind against them, and trade with grasp auto attacks.

I know this guide makes me seem like i hate mordekaiser, and for good reason. He is a scailing lane bully with a very strong kit, keep your distance, trade efficiantly and remember.. quicksilver sash!(if you don't want to feed morde buy qss before he gets level 6 and stay at your tower.)

Thresh is a late game support and you wanna play him top, make sure to manage your wave, keep your distance and suprise your apponents with a **** ton of damage! GLHF
