Poppy is one of the most underplayed and underrated champions in the league. She has high potential and can kill every one easy and in teamfights she can easly kill the enemy adc with 2hits. This guide is for every one new to Poppy and for them that want to start crushing their opponents!

Cons and Pros

Cons:
Underplayed
Almost no CC
Almost no Mana
Hard farming in the lane phase
Needs a little bit more skill
Stun only if you hit the enemy on the wall (like Vayne)

Pros:
High Burst vs everyone
Fast
Costs 450 IP
Underrated
Really tanky
Counters most champions

Ignite Why? Kill secure.
Ghost or Flash? You can use both, but I prefer Ghost to chase people down with the w, runes and shurelias!

Start with
Faerie Charm Sight Ward Health Potion Health Potion Health Potion Health Potion Health Potion] Mana Potion

or with
Faerie Charm Rejuvenation Bead Health Potion Health Potion Health Potion Sight Ward

or with
Boots Health Potion Health Potion Health Potion Health Potion

first/second back
Philosopher's Stone Sheen Tear of the Goddess tier 2 or 3 boots

build in to
Shurelya's Battlesong Trinity Force or Iceborn Gauntlet

after that
Liandry's Torment Rylai's Crystal Scepter Frozen Heart Muramana

Thats how I build her usually.

You can build her mote on defense if you need to counter other players.

In the quints I prefer movementspeed because you will have to chase the most of the enemy champions down and Poppys W gives you more moovementspeed so you will be the uncatchable killer!
In the marks I prefer use physical damage so you can farm better under the tower or harass them a little bit more.
In the seals I prefer armor/magic resist, depends on who you have top. (Most of the time I'm using armor)
In the glyphs you can use ability power, to harass more or armor to have better sustain!

Poppy is good with offensive and defensive mastery tree you can do your own masteries but I will show how I have them.

Use your ulti in teamfights on the enemy adc to burst him down or to the enemy supporter so you can't get hit by anything but him.
Try to not farm minions with q.
Try to stun the enemies on to your tower if they dive, ultimate, q and ignite them for the kill or if you are underlvled just run away.
Poppys w gives you damage!

For Poppy it is really hard until Level 4. She has low sustain, and almost no mana (500 is not really much).
Try to Farm most of the time under tower and call for ganks.
after like 10min of farming you should normally have like 50-90farm and 0-5 kills 0-2 deaths and 0-5 assists.
If the midlaner gives you the bluebuff get it as fast as you can and go gank or to your lane.

Hope I helped you with my first guide ever and learned you to play Poppy better :)
