Combos:
The aim of this deck is to get dinosaurs to the graveyard so they can be banished for monster effects.
Banishing Giant Rex allow you to special summon one to the field. Tyranno Infinity gains 1000 attack for each banished dinosaur. And the main monster in the deck Ultimate Conducter Tyranno can be special summoned by banishing 2 dinosaurs to the graveyard.
Cards to get other cards to the graveyard include: Morphing Jar, Soul Eating Raptor, Hidden Armory, Twin Twister, Foolish Burial, any xyz monster after using effect and Lost World.
Lost World is the best card for dinosaurs to defend themselves. Once per turn if your dinosaur would be destroyed you can send one from your deck to stop destruction. And it also summons a token to your opponent’s field when you summon a dinosaur. While this token in on your opponent’s field, your dinosaurs can not be targeted by any effects.
Since there is not trap cards in this deck Royal Decree allows you to always attack. Combined with a monster using Power of the Guardian and a monster effect to attack.
