Use skills like Draw Sense: Low Level or Sorcery Conduit to be able to draw Cerberus. Set any Enchanted Javelin if you get them in your starting hand to recover the damage, since you will also need to use some LP for Abyssal Designator.
Since Joey sometimes does not summon a monster with 1500 attack or higher, if you get first turn and you have Abyssal Designator, it is recommended to use it on your first turn. This is to make sure that you can use your skill on your next turn.
Stalling the duel
Once Cerberus is summoned, use spells to increase his attack to at least more than 2,000 attack. This is because Joey's monsters mostly don't have high attacks, if he used Polymerization or equip spell cards, it will further increase your Cerberus' attack.
Keep using spell cards until you are left with 0 cards in your deck, but don't use the Riryoku, Stop Defense and Ceal Bow yet.
When you have 0 cards left in your deck, Use Stop Defense on one of Joey's monsters and use the two Riryoku to further increase attack, then equip Shooting Star Bow - Ceal on the debuffed enemy to make it down to 0.
I'd say always make sure you have enough spell cards to activate to increase your Cerberus to over their highest creature. Then its easy sailing there.

I never use cerb to fight joey. For me, dino with dinosaur kingdom is enough. the headache is only time wizard. so I insert house adhesive to counter this. Once that time guy finish, joey just left to be defeat on final turn.
Just tried with a deck very similar to this one and he activated stop attack and my ceberus wasn't high enough on defense so he destroyed it with a lower level monster. I was thus dead in the water.
