Howdy, this is my build to Rugby Player Gragas. Of course you may doubt me for a second but don't kick it until you try it. It's a really amazing build which I got from bronze to gold with.

Play really aggressive and beat the **** out of your opponent and get fed. Easy peasy. Freelo. You're fat, abuse this advantage that you start the game fed.

Split push like a boss. There is no mid game for Gragas, only late game. Headbutt those towers until they're nothing but rubble and run around slapping their inhibs up.

Pros
-Runs super fast
-Hits like a truck

Cons
-None.

Ziggs- He is a tiny little yordle, all you gotta do is body slam him, you'll crush him.
Kassadin- Unlike other midlaners, Rugby Player Gragas can run laps around Kass, while Kass can silence you and your barrels, you can just beat the **** out of him with your head.
Kayle- Body Slam, rip off her wings, **** on her corpse. GG
Kha'Zix- He won't even get a chance to evolve, he'll rage quit before 6.
Lulu- Another Yordle, Body Slam OP.
Katarina- Her blades can't pierce your tough outer shell of fat. No damage is done to you, how could you lose.
Talon- No competition.
Yasuo- He literally can't get you off the ground to ulti you.
Swain- Literally, eat his crows for breakfast.
Orianna- She can throw A ball at you, whip out your balls to combat her, Jack Daniels and Bundaberg respectively.
Lux- Eat her laser for lunch.
Morgana- She can snare you, but being a rugby player you can just break through it.
Malzahar- Eat his voidlings for dinner.
Brand- Your fat should protect you from burns.
Nidalee- Get hit by her spears, pull them out, throw them at her.
Syndra- She has more balls than you, keep Jack Daniels and Bundaberg away and just Body Slam her.
Ahri- She can't charm you, you're not into beastiality.
Fizz- When his ult jumps out, grab it and eat it.
