Sry for my english..
Hello,my name is Aluzardzaar and i play 40+ champion.
I'm 1800 elo atm. But i prefer play with my ranked team.
My favorite jungler champion is alistar. WHY?
He has huge early domination in jungle and ganking-counterjungeling.

ALWAYS START BLUE! <--- AFTER WOLFES
Your team mates help you..pull and a little bit dmg!
After blue you must gank top or bot.
You must gank behind the enemy prefer this combo: Headbutt wait 2 sec after Pulverize this is a hard cc from the enemy and you have 3 - 4 sec to kill the enemy.
If you got kill 1st or 2nd recall buy Oracle's Elixir. <--- IMPORTANT
( you can't gank without clearing wards.....)
I prefer ganking i think better than farming... But you need farm for exp...

Alistar is a perfect jungler for invade,cuz he can cc the enemy team and easyly smite the buffs.
STOLE DRAGON!!! I use this combo for stole dragon,baron etc...
If the dragon have 600hp or lower use this combo: Headbutt,Smite after flash over the wall..
If the dragon have 1000hp or more use this combo: Headbutt,Pulverize,wait 1 sec if you can and smite...after flash over the wall..
MORE IMPORTANT ON RANKED! CLEARING WARDS!

Runes: i prefer take armor on seal , magic resist on glyph , ms 1.5% quintessence , and any dmg on mark.
This rune build prefer the mobility. If you buy boots of mobilty you just running in the jungle like a race car....
And its very good, u can easyly counterjungling..

Summoner Spells: I use smite + exhaust.
Why SMITE: Because you need to stole dragon,baron,or just a golem or something..
Why EXHASUT:Because i always ganking the enemy behind and i don't need flash because i have headbutt, pulverize, exhaust combo = 100% DEATH Exhaust -magic resist -armor!
If you use flash you can gank like this: flash behind the enemy headbutt pulverize, its a safe combination but i prefer use exhaust.

If you use this build you have 264+ armor and 64+ magic resist SO YOU ARE VERY TANKY!!!
You can tank in the teamfight with you ultimate ( -70% damage reduction ).
You must start the teamfight with a headbutt, pulverize combination after ultimate.
Use exhaust just to AD CARRY!

I very very like the gp / 10 items, because you got gold without farming and you can more gank and a little bit less farming.
This itemization you'll tanky,little bit support because you have 2 using item its very good in the teamfight you can slow the enemy,reduce the attack speed and you can chase the enemy very easyly with Shurelya's Reverie. And you have Frozen Heart -20% attack speed on aura ( 1000 range ).

ALISTAR VERY IMPORTANT SKILL COMBO!!!!!
If you have to chase an enemy or you just have to cc someone rly important to use this combo!
If you use Headbutt you just spam pulverize and the enemy is instant knock up without push.
You can see this video

I use 9/21/0 for more tankyness and a little bit dmg.
