You need fewer D-Heroes and more helper Warriors. I know its tempting to just throw some D-Heroes together and call it a deck but that tactic just doesn't work. Take a close look to the D-Heroes. Which D-Heroes work together the best? Just because cards have the same theme doesn't mean they will work well together. Just look at all the unused Chaos support from Invasion of Chaos or Neos and the original E-Heroes. What I'm trying to say is that you need to focus the deck around a few cards rather just stuff it to bursting with D-Heroes and their support. Most D-Hero support sucks. I recommend you use generic Warrior support like Reinforcements of The Army and Th Warrior Returning Alive. The trap-based support is doomed to fail due to the recent prevalence of Royal Decree and Jinzo. Put in more useful traps like Sakuretsu Armor or Dust Tornado.
