Since Odion Lvl 30 does not use a card to destroy Mythical Beast Cerberus or prevent it from gaining ATK, you can win a duel against him with high Duel Assessments with using a High Score Cerberus deck. For an example deck and how to use it, check the link below.
You can do the 10-trap fight against ANY opponent, such as one of the Standard street duels. The traps you use do not have to be effective, merely "activated" (even if their effect was wasted). There are lots of simple traps you can active at will: Snake Fang, Shield Spear, Secrets of the Gallant, etc. Just create a deck with a few strong 4-star monsters, then fill the rest with simple traps.
