Yuigioh advice

yo!I am an awesome yugioh fan,and I got loads of advice for you.If you are just a beginner, just go to a nearby shop to get one. Tell you which deck I fancy,(Dinosaurs' Rage).AWESOME dinosaur cards in stall!!!!!!!!!!!!!!!!Best level 4 creature,(Black Stego) has an awesome effect.It turns to defence position when it is attacked.Let your opponent fall for the trick and he is in hot soup.Another one is the (Ultimate Tyranno).If it is in attack position at the beginning of your battle phase ,you must attack ALL of your opponents creatures using it.The rest are kept as a secret,for you to find out!
