This is a combo deck so it's almost a guarantee that you'll have a strong board at the end of your turn. The good thing about this deck is that the combo pieces flow and it's very consistent.
If you have 2 level fours, you can opt to xyz summon Gallant Granite and use his effect to search out a rock monster, preferably an adamancipator tuner so you can further abuse their effect. Then summon out monsters from your extra deck for that otk. That extra deck is full of monsters that could easily counter everything your opponent throws at you. Even if they nibiru you, you can still somewhat play through it cause that's how good the deck is. This deck rocks.
