The main focus of this deck is to get Mythical Beast Cerberus out on the field and buff him up with Shooting Star Bow. First thing you want to do is take more than 1800 LP damage to use your draw sense and get Cerberus to your hand.
In this duel you actually want to lose LP and end up with just 100 by the end of it so you'll be using a lot of your spell cards for that. So get Cerberus on the field and start activating your spells to get spell counters on him. Use Mooyan Curry, Abyssal Designator, Twister, and Blue Medicine to work your life points to 100.
Keep your equip cards in your hand until your life points are where you want them to be. Having only 3 spell zones means you need all 3 open to play them. Now if your opponent has cards that deals damage to your life points then don't worry about lowering it yourself. A good combo is using Murmur of the Forest - Stop Defense - Twister - then a field spell.
Once you have spell counters on Cerberus use Riryoku to give him a massive attack boost. After that you have 2 ways to completely wipe out your opponent. Use Shooting Star bow to attack directly and deal over 9999 damage. Or if you don't have Shooting Star Bow use Stop Defense to force your opponents monster to attack and deal damage that way.
Use this deck against Yami Yugi, Rex Raptor and Weevil Underwood for the best results. You can get 5000-8000 points easily fighting against these 3 characters. Avoid fighting other characters.
