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.
Check the example traps you sausage.
Use a mako or dino deck, something that makes sure you can lock them down so you can freely do your thing.
I had around 12 traps, and 6 monsters(around 1650/1750 atk) with field spells like Umi or DK added 1 BEWD for overkill, 1 shard so i can keep up if he's close to decking out, the other 2 can be any support spells or traps(non continuous).
