Dinosmasher's Fury, the 38th Structure Deck for the Yu-Gi-Oh! Trading Card Game, will be released together with Machine Reactor. This Structure Deck sports 41 cards, so it's quite likely that you will also get to find a monster in it that belongs in your Extra Deck.
The Dinosaurs are using two different strategies to win games. On the one hand, they have a number of options to summon a multitude of Level 4 Dinosaur Type monster, which will in turn give you access to Rank 4 Xyz Monsters. On the other, they can look forward to a brand new boss monster: Ultimate Conductor Tyranno that can be summoned rather easily; all you have to do is banish 2 Dinosaurs from your Graveyard.
This is a lot easier than it sounds as the other new card is a Field Spell Card that will fill your Graveyard quickly. Lost World prevents your Normal Monsters from getting destroyed if you send a Dinosaur from either your hand or your deck to the Graveyard. Additionally, it weakens all Non-Dinosaur monsters by a whopping 500 ATK and DEF, so you can easily overcome your opponent's monsters in a battle. It also Special Summons tokens to your opponent's side of the field and as long as they control such a token, they cannot target any other monsters on the field. In essence, this card will provide the archetype with a very big boost and give your opponent a very hard time cleaning your field.
The already mentioned Ultimate Conductor Tyranno boasts an impressive 3500 ATK and it can change all of your opponent's monsters to face-down Defense Position. On top of that, it can attack each of them once. Even if it flips all monsters face-down, it will deal a lot of damage as you can destroy Defense Position monsters with its effect and inflict 1000 damage to your opponent's LP. Obviously, this card can win games all on its own, so it's no big surprise that a booster box of the new Structure Decks will contain a few more copies of Dinosmasher's Fury.
