Snore-Max Snorlax - Galaa

Guide

FIRST PICK

Tackle is good and better than Rest for farming in the beggining of a game, it also slows whatever it hits and has a good AOE.

FIRST UPGRADE

Flail increases your attack when your low on HP but also basically boosts you, it also give you a little speed boost for a short time, cool to chase ennemies when they are low.

SECOND UPGRADE

Yawn is useful to stop annoying ennemies and kill them easily, instead of them dashing 100 times on you, he'll sleep waiting to be killed. (like Zeraora). I like Block, but I don't know, it's not as useful as Yawn I think, you can try it out if you want :)

UNITE MOVE

Power Nap is the best thing when your in team fights and your low on HP, because they will all focus on you, but instead of dying you recover all your life. (and personally I never died when using Power Nap in a middle of a big fight, even two UNITE move could not kill me I think)

ITEMS

The Focus Band pairs well with Flail that goes brrrr when you have less HP, but also goes well with your UNITE move, since you want to activate it when your low on HP.

The Aeos Cookie is useful late game, and late game, if you have scored a lot of goals, then your the most chunky Snorlax on the battlefield and can take 3 UNITE move without dying. (using your UNITE move as well of course)

The Rocky Helmet is useful when the opposing team has a lot of pokemons using Atk. They will attack you but they will lose health over time ! And you have more health than them, so it's very useful, and remember that it also pairs well with your UNITE move, because the Rocky Helmet can also stack others UNITE move to deal enormeous damage :)

The Slow Smoke is just there to pair well with Flail, let me explain ;
You run towards your opponent with the Flail, you reach him and use the Slow Smoke, and then you can Yawn to put him asleep so your ally is reaching him too.

(This build of Snorlax is Bottom Lane because since there's Drednaw, having a shield is always useful with a Chunky Snorlax)
