This is my first tutorial, my English is really horrible is not my first language. I'll try to explain my two builds and how they work. Basically, the poppy is a hero to kill Aps and Ads easily with your combo Q + E (Wall). And your Q can do serious damage to tanks. Play Video here can see the Combo of poppy. ( Poppy AD ) but the same combo.

For Poppy Combo Kill runes has to increase Armor Penetration and some Defense and Magic Defense to not die very easily. This will give a good start to the game.

9x9x 9x 3x
For the Poppy Tank Killer is a good start with enough Defense, Magic Defense and Dodge which is a basic tank.

9x9x 9x 3x

I really like Ghost and Exhaust. Exhaust is good for ganks, flee from the enemy and stop some AD heros.

Ghost in the Poppy is great because it runs well with his Paragon of Demacia can easily escape some gank because of being without ward or your friends do not call mia. It is also very good for when you go running after someone and having to get to your side to use Heroic Charge to hit the wall.

GhostExhaust
but you can put Flash, or even Heal if you like but I do not recommend.

For Poppy Combo Kill, the best items are those however with the game can change some things. for example you want to continue killing but you die too much. you can change the Phaton and Blood for a few items like Banshee Veil and depending one Warmong, Thormail or Force of Nature.
this is your final build.

For the Poppy Tank Killer, you can not change much the items because they are already the maximum balanced. but you can change as the game dictates, 5x5 example, has 3 ad, 1 tank, 1 ap. can something that can change the magic defense and put defense . and the same thing occurs if many aps and trade items of defense to magic defense.

But in two cases the Trinity have to be build in and grab it as fast as possible.

Passive:- Any damage dealt to Poppy that exceeds 10% of her current health is reduced by 50%. This does not reduce damage from structures. This is the power used against any AD. it reduces 50% damage taken if he Execed 10% of her total life. why do some poppy tank.

Devastating Blow:- Poppy enhances her next attack so that it deals 20 / 40 / 60 / 80 / 100 (+60% of ability power) plus 8% of her target's maximum health in bonus damage. The bonus damage dealt cannot exceed 75 / 150 / 225 / 300 / 375. This power is generally used to kill and can kill tanks easily

Paragon of Demacia:- Passive: Upon being hit or attacking an enemy, Poppy's armor and damage are increased by 1.5 / 2 / 2.5 / 3 / 3.5 for 5 seconds. This effect can stack 10 times.

Active: Poppy gains max stacks of Paragon of Demacia and her movement speed is increased by 17 / 19 / 21 / 23 / 25% for 5 seconds. Great to be able to run a meeting with his enemy, increases your defense and destroying the attack, used also as a farmer.

Heroic Charge:- Poppy charges at an enemy and carries them for a short distance. The initial impact deals 50 / 75 / 100 / 125 / 150 (+40% of ability power) magic damage. If they collide with terrain, her target takes 75 / 125 / 175 / 225 / 275 (+40% of ability power) magic damage and will be stunned for 1.5 seconds. This is the power used to stop your enemies against the wall and used to help give the Boost Q. also be used to be a poppy APs and cause a high damage against the wall .

Diplomatic Immunity:- For 6 / 7 / 8 seconds, Poppy is immune to any damage and abilities from enemies other than her target.

In addition, Poppy's attacks deal 20 / 30 / 40% increased damage to the marked target. Damage increase applies to summoner spells and items used by Poppy. His power to be able to dive tower, great for teamfights, used to kill a hero because it increases up to 40% of its damage to it, and to escape if used correctly it negates the damage from the other heros without your ultimate .

Poppy Combo Kill.

Pros:
- Can kill Easy
- Good Damage in Early with E
- Passive can make you survive
- The ult if used correctly can make you kill the ads/aps and run safe
- Fun to Play

Cons:
- KS so much
- CC and u die
- Silence can make u suffer
- Ranges kill u.

Poppy Tank Killer

Pros:
- Good Tank
- Passive + Defense = Imortal
- Kill with Trinity
- Ult can tank a entire Team.

Cons:
- KS a Lot
- Silence can make u need to leave to not die
- Ranges still can kill u with madred.

In teamfight all you need to use your ult in a Tank (less Rammus or galio) or an AP with no mana. And kill first the Carry and Mages. Talk to your team not target the hero with the ult. Play Video this is one video, can teach how use the ult and see the power of poppy.

Poppy not good farming, so you need try to give the last hit in all minions possible. good way to feed is use your Q in minions. and kill a lot of heros.

Ty to Read my first guide, comment and give some repplys. ^^.
