Dino's aren't the most competetive deck to play right now but surely are a lot fun. They don't make the most impressive boards but can make some that easily win you the game (They also have a OTK, for those who want). This Dino deck really depends on going second and going first with the wrong cards in your hand can hurt sometimes.
Lost World Dino is one of my favorite decks and I will show you why. Dino's have a very simple strategy; putting big beatsticks and negates on the board. This is mostly possible with ULTIMATE CONDUCTER TYRANNO, the EVOLZAR duo and PANKRATOPS. The main plays start with OVIRAPTOR and a combination of MISCELLANEOUSAURUS and/or LOST WORLD in your hand, this is why you play 3 FOSSIL DIG to search you combo starters. I play 6 handtraps to disrupt opponents plays and 2 to get rid of powerfull boss monsters.
The OTK is having an token on your opponents field with LOST WORLD (OTK is still possible without token, you opponent just needs a monster on their side of the field), getting DUGARES on the board with UCT, activating DUGARES's effect to double UCT's attack, linking DUGARES and another card away for PENTESTAG (that points to UCT), destroy a monster in your hand to change your opponents monsters to face down defense position, attack every monster with UCT for 7000 piercing dmg (and directly after all monsters are gone.
Any questions can be send to me, will do my best to answer them quickly.
Thank you and have fun playing!
