To put it simply, this is only a Lost World Dinosaurs deck that techs Jewel Beast - Argosaurus to help further your plays. The deck uses 3 Babycerasaurus and 2 Petiteranodon so that you can pop them with Argosaurus and search more Dinosaurs from the deck--mostly your Souleating Oviraptor.
Due to Argosaurus also being a Level 1 monster, you can summon it with Miscellaneousaurus, and if you sent Misc to the Graveyard with its effect first, your opponent will not be able to stop Argo's effect from going off. You still want to go second (obviously), since Argo's effect can make summoning Link Monsters easier, potentially allowing you summon your Link 3 and 4 monsters.
