Dinosaur-type monsters pumped up with Rex's skill, Dinosaur Kingdom, are the main force of the deck. Those monsters have 1900 ATK and will never be beaten by low level monsters unless they equip ATK boost spells.
When you use the deck, you need to use Rex Raptor to set the "Dinosaur Kingdom" skill that is acquired by leveling Rex Raptor up to 4. Jurassic World boosts the ATK and DEF of Dinosaur-type monsters by 300.
Twister is necessary to fight against the deck. Two Dinosaur monster become just normal 1600 ATK monsters if the field spell is destroyed, and it is easy to beat them.
Use two effect monsters
The Hunter with 7 Weapons and 4-Starred Ladybug of Doom are cards to beat 1900 ATK Dinosaur monsters. The Hunter with 7 Weapons will have 2000 ATK while battling against Dinosaurs, and the Ladybug's flip effect destroys all level 4 monsters your opponent controls.
