Use the lower level monsters and keep destroying keith's monsters. Don't attack if he has a face-down trap since it could be rare-metalmoprh. Set a magnetic mosquito if you think he will tribute summon either blowback or barrel dragon. Use acid raid if you don't have mosquito to destroy his tribute monsters. It's best to summon BEUD during second to last turn to avoid it getting destroyed early. On the last turn, summon vassal and use the union attack combo.
Summon either the hunter or jerry and destroy keith's monsters when they are in defense position to not lower his LP. If they are summoned in attack position, switch it to defense using otohime on the next turn. Acid raid if their attack is higher than yours, or mirror wall to defend as well as reducing your LP. Lower your LP to more than half of keith's LP and keep destroying his monsters so the BEUD can get a direct attack to deal 10,000 damage after equipped with sword of deep-seated.
Since the ATK of Twin-Barrel Dragon is 1700 and same to that of Axe Raider, the highest ATK level 4 monster you can get, you need to use equips spells or other ATK boost cards to get your monsters to defeat the dragon.
Use Spell/Trap removals
Destroying Keith's Machine Conversion Factory, Second Coin Toss, and Rare Metalmorph is important to help your monsters to beat Keith's Machine monsters.
The same thing with Leotaur, can't be affected by Angel 07's effect.

The graverkeeper's vassal's effect will not be canceled. Because effect of 07 is "The effects of Effect Monsters """cannot be activated""", however, vassal's effect is a "Sustainable effect", which do not need to be activated in Yu-Gi-Oh rules

i hope you know that while Angel O7 is on the field graverkeeper's vassal's effect to turn the battle damage into effect damage is negated and thus it's treated as battle damage
What Mikey said. Unfortunately to get 3 duname witch you probably need to spend at least $150

Angel07+ riryoku field beats any deck including keith and seto,
add up union attack card x2 and gravekeeper's vassal and secret passage to get 8k assessment score
I don't use Cerberus anymore
you could also add megacyber for a quick comeback high attack monster to defend your life points
