This decks main strategy is to try and outlast the opponent by banishing their combo pieces with Necroface, and getting tons of monsters onto the field with The Chaos Creator and and Chaos Zone. If you need to end the duel faster, we also have Geomathmech Final Sigma, Black Luster Soldier - Envoy of the Beginning, and Gren Maju de Eiza. If you want to make your opponent hate your very existence, we have Number 90, Number 23, Number 68, and Macro Cosmos.
However, if you want to use Macro Cosmos, make sure you already have The Chaos Creator on the field, and also preferably Chaos Zone as well. This way you can just recycle your monsters endlessly. However, it only really works if you already have a lead and want to prevent a comeback. Also, this lets your Gren Maju easily get tons and tons of attack.
This deck does take 2 or 3 turns to really pop off, so that's why we have cards like Geomathmech final sigma to help stall until you can get Chaos Zone and The Chaos Creator.
