Well, a dinosaur deck in the Genesis format without Jurrac Meteor Engine...
The reason is simple: Jurrac is very expensive, this deck tries to be cheap, so I will suggest substitutions for some cards as well.
The idea of the combo is to end with the conductor on the field, Laggia, Dolka/Transcendosaurus. The other monsters from the extra deck can appear depending on the hand.
The deck is focused on Pop the Baby, so True King is there for that purpose, as are Diagram and Jurrac Meteorus/Ground Xeno. The Ryu-ge cards are for searching, unfortunately Kairo becomes a brick in your hand, unless you destroy it with a True King. Remember that Kairo can summon itself to the field for free from the graveyard, so with a turner it can still be useful. The War Zone allows you to do many things, like drawing a Dino monster to your hand like Baby Dino and starting the traditional Dino combo, or even drawing True King Disaster to summon it with 2 Earth monsters. In this process, you can send Kairo to the Graveyard or Ban Zone. Leaving QQ in the Graveyard can also be used to summon it with a True King monster from your hand due to its effect. In this route, you need to make Rank 9 XYZ Summons.
Ultimate Slayer tries to deal with the field, can remove negates from the field before the combo starts. That said, the deck can also work with a copy of Misc. In this case, you need to remove practically everything from the deck to fit it in, only keeping Upstart Goblin to draw cards or Laggia as the final boss of the Extra Deck. Then, to try to draw Misc more easily, you use Small World in the deck, you also can run dark ruler no more instead do be able to combo more freely.
