The main goal of the deck is to stay ahead by being focused on not losing during Battle Phase, the deck thus has a lot of one for one trades to keep slightly ahead - with this eventually accumulating enough that you win.
Fossil Dig is the deck's key card, as it can grab you whichever Dino you need for the scenario you are in. It should generally always search for Destroyersaurs first so that all of your Dinos have their 300 ATK boost.
The deck's biggest push is Hydrogeddon, who can gain a tremendous amount of advantage during battle, especially in conjunction with Solidarity. It is important to note that this does not conflict with Royal Oppression - which cannot stop the Damage Step Special Summon effect of Hydrogeddon.
Since you have Brain Control you can play all the usual Synchros in case you steal a Tuner, but beware that it could conflict with Solidarity. For the side deck the only non-optional card is Element Saurus, which will be sided in against monsters with float or flip effects (such as Ryko). Mist Body is also useful tech option as it makes your Hyper Hammerheads and Black Velocis much bigger threats.
