Suggested by Sonic Davide Yamazaki is a talented buddyfighter. He has a lot of cards at his disposal and multiple decks. Drum Bunker Dragon is one of the toughest monsters in the whole series and he has had quite a few super forms. The problem is that they rarely get to ever do anything because they tend to only appear for half an episode. Davide has one of the 7 Omni Dragons as his Buddy (Albeit the dark clone version) so that should be enough to give him the slight edge here. I don’t think Drum will be able to withstand the army. Davide Yamazaki wins.
