How to play

(Short Explanation)

If you are the first pick in your team means you got an advantage for your team to counter their picks.
why?
Because Amumu is known as a jungle and as you are the first pick and you going as support, the enemy team will take a counter pick for you Amumu because they think you're the Blue team jungle, so your team jungle has advantage to take a counter pick of their jungle, and a good jungle gives good advantage to his team to win.

Most of the times when you pick the enemy team will pick as a counter pcik to Amumu

Amumu is not a main support but you can play him as a new meta support because of his double stuns that gives you time to kill your enemy once you reach Lv.6 and you can unlock your ultimate Curse of the Sad Mummy.

You can only engage the fight with your Bandage Toss if you fail it you gotta be playing safe and wait it to be ready again.

You have to ping always your adc to get ready for your engagement, if you see your adc is weak or not going to fight so don't because Amumu can't skip once he land his Bandage Toss on the enemy champion unless you have the ultimate Curse of the Sad Mummy, you can use it and run with the boost of the Nimbus Cloak that gives to you.

With Amumu you gotta very patient, your bot lane will be pushed hard from lv.1 to Lv.6 because you can't poke the enemy champion, you gotta be patient until Lv.6.

Once you unlock the ultimate Curse of the Sad Mummy, you gotta be 2 things at once, you will be supporting bot lane and mid lane if needed, How?

Once you unlock your ultimate Curse of the Sad Mummy, the enemy champions knows that if you land your Bandage Toss you gonna follow it with this combo Despair >> Tantrum >> Curse of the Sad Mummy + Ignite or Exhaust with your adc damage and abilities the kill is 100% secured, so your enemy champions will take distance from you, if you see that you can't engage the fight then roam to the mid lane and gank for your mid lane.

Try to get fast the cool down reduction items first because it will help you to reduce your Curse of the Sad Mummy time to use it often, without the Curse of the Sad Mummy your engagement are 50% kills.

That's all if you do this, your game is easy win because your team will be having an Amumu support, Tank & jungle, your team will be like having 2 jungles late game.
