You hate that game in which you are playing good, but that Yi is just too fed.Nothing you can do to that Mordekaiser that will just decimate your entire team alone?That Katarina will press R and kill your entire team.Here is a list of how to counter pubstompers while leveling and at level 30 plus some champions that counter them pretty hard.

#1 Pubstomper ''es numero uno en BR'' Mordekaiser

Mordekaiser is a pretty decent hero and if left uncontrolled he can farm a lot plus if he gets a few kills he will snowball so hard there's nothing you can doto stop him.Even in ranked lots of people have trouble with the giant metal master Mordekaiser.
Mordekaiser is an ap carry/tanky ap/tank type of character with a decimating ultimate.

*Items that counter Mordekaiser:
-Hardest counter to Mordekaiser is magic resistance.Everything you can get your hands on will do wonders against him.
-Quicksilver sash is Absolutely AMAZING and works wonders against the Master of Metal:You use your ultimate on me?K ill just press 1 and cleanse it.
-Mercurial treads,Banshee and Force of Nature are also great choices against Mordekaiser.

One of Mordekaiser's weaknesses is that he is very weak if he gets ganked early on.He is very prone to ganks l because of no innate escape,so if he wastes his flash just go and destroy him.

As well if you are fighting him 1v1 fight him AFTER your creep wave is dead so he wont get full shield just by using AoE.

If you feed Mordekaiser he will develop into a great beast that will eat you,your teammates and your family but if you counter him early on,gank him a lot and you don't let him farm he will remain a metal toy.
-Udyr.
*Garen.After the buffs Garen top counters Mordekaiser so hard its not even fun.If you deny his creeps and won't let him farm and buy armor you sill simply burst him in seconds.




#2 Tryndamere the Barbarian

You hate it when that fed Tryndamere 2 shots your entire team and when you almost kill him he ults,kills you too and then just gets away.Yea i hate it too.But you can counter that pretty easy by not letting him get fed/farm. Generally this concept applies to everyone.Not farmed=pretty much useless. The question is how to deny him the farm.Well that's pretty easy.Tryndamere is countered by two things: Crowd Control and Ignite.

Crowd control counters Tryndamere so hard its not even fun.He ults?Okay you taunt him and wait till ult is out.He ults?okay drop stun tibbers + igniteon him and he dies.

*Tryndamere is countered by armor especially by Thornmail so if you are a tank/bruiser DO GET thornamil and stomp on Tryndamere.

Champions that counter Tryndamere:
-Anyone with a CC,silence.

#3 Master Yi


Yey the samurai that Presses R and Right Click to win.Hard to counter?Nah,pretty easy actually.He is almost the same thing as Tryndamere only that he doesn't have an ultimate that makes him invulnerable.So CC counters him EVEN MORE.Besides being incredibly squishy YI is also hard countered by exhaust because
his main damage comes from Autoattack.In case he will build Quicksilver Sash to cleanse it your team has to focus him as fast as possible because he can decimate an entire team pretty fast if left unchecked.

*Yi is countered by armor and stuns as hard as tryndamere is.

Champions that counter Master Yi:
-Anyone with a Brain.
