This deck can take you to over 9999 LP damage easily if you get your Cerberus early on.
What you want to do is to stall the duel and take Bakura down to less than 500LP as fast as possible. Using Dinosaur Kingdom with any of the dinosaurs in the deck can stall the duel quickly. You'll never leave Bakura any monsters on the field, or else he'll summon his 2k ATK monster.
If you take his LP down quickly, you don't have to worry about Ectoplasmer. Magic Jammers are there also to prevent Bakura from exchanging your Summoner of Illusions (he always do) later on, also to prevent Ectoplasmers. Gravedigger Ghoul is there to remove the 5 turns limit.
You'll buff your Cerberus as much as you can while maintaining any dinosaurs on the field to destroy Bakura's monsters. Later on you can summon BEWD to switch Jurassic World for Yamoussoukro, further boosting Cerberus. Stop Defense prevents Bakura from saving himself in your last card, thus making you lose by deck out.
Jurassic World for Yami* - Sphere Kuriboh is there to prevent Bakura from attacking your face-down Summoner of Illusions, which you must always remember to set when you have two cards left to draw. Depending on how boosted your Cerberus is at the last turn, you can both summon BEUD by flipping Summoner and Riryoku it twice to further boost your Cerberus, vice-versa in case your Cerberus is weaker.
@Koz It's pretty consistent. My best streak of 7k+ DA was of 12 duels, usually breaking the streak due to Gravedigger Ghoul not showing up soon enough usually in 5-7 duels.
