Hello, this is my Poppy guide, in here you will learn how to wreck the face of EVERY DAMN CHAMPION in the League of Legends with Poppy.

EVEN IRELIA!!!

I use classic runes for Poppy :
Greater Mark of Attack Damage x9 - for easier last hits.
Greater Seal of Armor x9 - for armor(you'll definitely need those at top lane).
Greater Glyph of Scaling Magic Resist x9 - some magic resistance for mid/late game.
Greater Quintessence of Movement Speed x3 - for nice movement speed boost( Poppy's main gap closer).

Other valuable choices :
Greater Quintessence of Vigor x3 - really helpful vs champions like Yorick in early game.
Greater Seal of Gold x9 - little boost of your gp10.
Greater Mark of Desolation x9 - vs heavy armor enemies.

My poppy mastery tree is a bit unusual 1/15/14.
It's based on MS, GP10, survivability :
Summoner's Wrath , Hardiness , Vigor , Veteran's Scars , Wealth , Swiftness .

Well if you prefer, you can take 21/0/9 mastery tree for more damage, but really u have enough :D.

The build from above really doesn't need changes it works vs any team.
Still there are some valuable exchanges:
Hextech Gunblade >> Bloodthirster.
Last Whisper >> Black Cleaver or Phantom Dancer or Quicksilver Sash.
Avarice Blade >> Youmuu's Ghostblade (instead of Last Whisper again).

Classic
Diplomatic Immunity >> Devastating Blow >> Paragon of Demacia >> Heroic Charge.

vs heavy AD
Diplomatic Immunity >> Paragon of Demacia >> Devastating Blow >> Heroic Charge.

Rank A
Ghost + Ignite - Ghost gives you insane MS boost that can be used during Diplomatic Immunity for fast catching up with your victim and Ignite damage is increased by 40% as well if used on the target with your ult on.

Rank B
Flash - if you think you won't need the bonus MS from Ghost.
Exhaust - very helpful in 1v1's but also can be used in other smart way.If enemy team has TONS of CC then u can exhaust the enemy with less CC and ult him , so he won't be able to kills you meanwhile.
Cleanse - pick that vs many CC's.
Teleport - very situational spell, but it can save games!By teleporting behind enemies on ward can win team fight, also useful when split pushing or backdooring.

Pros

+

best late game carry

+

WRECK FACES!

+

TONS OF DAMAGE!

+

brings fear in enemy and they split like sheeps

Cons

-

early game weakling(and late game god xD)

-

vulnerable to CC(if well played not a big problem)

Use Diplomatic Immunity on support or low damage/CC target and wreck the faces of their carries.
If enemy has huge amount of CC then you'll need a little help from your team:
ask some1 tanky to initiate instead of you and wait til your lowest CC enemy use his CC on your mate then rush in the team fight and ult that enemy instant and wreck faces.

If played well Poppy can carry +70% of 1v5 games.

Just last hit don't push and let enemy harass you, then enemy jungle appears, they tower dive you, you use ult on one of them AND BAM SUPIRSE B*TTS*X DOUBLE KILL!!!
