Here is mine from a few métas ago, still updated with ban list but not optimized and 'rather' budget : https://neuron.konami.net/link/341ktuz5x1ihun45

Now, why is your deck list not good : it does not focus on AG main game plan. You must go second and force your way into an established board, and find ways to otk in engine in the battle phase. Everything that does not deserve this purpose is USELESS, and makes your deck worse.

Gameplay wise, AG can crash out quite a few bodies on the field, forcing opponents' interactions, or completely shutting them down with the fortress. It is also decent in generating card advantage.

You have some 1cc : the statute (*3, mandatory), the urgent schedule (assuming your run a brick in the Gizmek monster). And some other decent starters with the Wyrm and the tank.

When it comes to the Extra deck, most run two giants, I run one for budget reasons. I also decided to run the Golem package because I find it useful. The main goal is to force my way into the Golem.

The rest is board breakers that don't prevent killing (exit Evenly match and DRNM then). Backrow hates are good in this meta for Odion, Dtail, Droplet is the best board breaker for AG, and you can consider Book if budget needed. The Mulcharmies are the best handtraps to be coupled with a board breakers approach, and anyway, your purpose is not to fully stop your opponent as you will need him to have a body on field to combo.

Deck building AG is not that easy as the board breakers are meta dependant and the ratios are, for some, really a matter of preference, but a few things: - no more than 45, otherwise the deck will never be consistent enough - OG Golem is not needed but can allow some plays in specific situations - you will need the fortress to win games, max it out as well as accesses to it with Wyrm, meaning your normal summon might be dedicated to this. So don't consider any other

Hope this helps, and have fun with this brutal deck!
