This is not an in-depth guide to explain every aspect of the champion and how the mechanics work cause i honestly don't care about that i just want to post a simple guide to get a good score.

I will update this later with pictures/scores.
Your Q is your power house ability use it when ever you can.
Use W To run away or to chase champions or at low levels for damage.
Poppy's E Is amazing use it to save teammates stop an ulti but mostly its a stun.
With her Ulti you can 5v1 kill 3 and make it away full health, tower dive if you know you can get the kill and get away, charge them out of tower range then q for that extra get away. Dont just put her ulti on some one for the extra damage sure it's nice and is worth it from time to time but if there is a group of them pick the one that does the least damage.

The items are pretty set no real good reason to deviate.

Over all it is simple follow the top and if you know the character you should be going very positive.
