Apex Predator jungler Garchomp - Heion

Guide

First, let's talk about the strengths and weaknesses of Garchomp and why I choose to play him in jungle.
- Lacks mobility in early game
- Long wind up damage skill in early game
- Melee with short ranged skill in early game
- Technically, weak early game, can't fight any other pokemons
+ Great crowd control
+ Decent damage and sustain
+ Has one of the best UNITE move in the game

Items:
1. Muscle Band: Synergizes well with your passive, also gives flat attack speed stat.
2. Float stone: Gives a lot of movement speed, helps you roam around a lot faster, very essential for a jungler imo.
3. Attack Weight (optional): As Garchomp jungler, you want to go behind the enemy line and use Dragon Rush to push them back to your teammates. May as well sneak in a few dunks while doing that.
4. Other options to replace Attack Weight: Weakness Policy, Razor Claw, Scope Lens

Why jungle and not the other lanes?
Garchomp can't really fight anyone until you get level 6 with either upgrade of the first skill, you the safest way to reach that point is to farm in jungle.
**Pick Sand Attack first, kill the first wild pokemon, use Bulldoze at 9:45 near either buffs to deal damage right at the moment they spawm.**
You can avoid Garchomp's weak early game by playing him in jungle. If you play him in lane, Garchomp won't be able to catch up to his enemies and kill them, but when you play jungle Garchomp, you can: Clear your jungle to reach level 5, then use a jump pad to jump over the wall and gank your enemies from behind, use X Speed, Sand Attack to speed yourself up, Bouffalant buff to slow them and kill them with your team as they try to run away. With the 2 speed boosts and a slow, you can pretty much guarantee a kill.
(Take Float Stone to do this even better)
(Avoid 3v3 fights if possible, after all, this is still your weakest state)
If this doesn't work out, just go back to farming.

Playstyle:
+ Farm.
+ Dash over walls to sneak in some dunks and upgrade your Attack Weight.
(Caps at 6 stacks)
+ Steal enemies' farm, scale to late game and win games through Zapdos.
+ Use your CCs and displacements to team fight, avoid solo fights.

*Note:
+ Can also take Eject Button for some flashy plays or X attack depending on your playstyle and teammates.
+ Your basic attack and skills all deal AoE damage. Always pull 2 wild pokemons together so you can kill both of them quicker.
+ Early game, use Bulldoze before Sand Attack to maximize Sand Attack's buff time.
+ Prioritize Rotom if your team is winning, Dreadnaw if your team is losing.
+ The more pokeballs you have the slower you dunk, try to hold only 15 or less at once.

Game plans:
+ Contest the bee flock with your team when they spawn.
+ At level 6, take either upgrade. I prefer Dragon Rush because I can push my enemies out of their safe zone so my team can kill them easier, and you can hit more enemies with this skills.
+ After that, use DR/Dig to go over walls and sneak in some dunks whenever you can to upgrade your Attack Weight.
+ Around level 7-8, Rotom will spawn. You can solo Rotom very quick if your team manages to distract your opponent. Try to push Rotom toward your base with DR and/or Dragon Claw while doing that.
+ Always take Dragon Claw instead of Earthquake. (Correct me if I'm wrong here, but Dragon Claw is just way better).
+ Look for gank whenever you can, Garchomp is a better team fighter than a solo duelist. Save your UNITE move to help your team contest important objectives such as bee flock, Rotom, Dreadnaw.
+ Either solo Zapdos while your teammates distract the opponent or use your UNITE move to contest Zapdos with your team and win the game.
