Hows my elemental hero deck looking?

Unfortunately the deck is not very strong. Sure you have lots of E-heroes but they do not have the effects that you need to pull off a win. If you insist on keeping this deck, then you need cards that will defend your E-heroes, more Sakuretsu Armors, Mirror Force, Dimensional Prison, and Call of the Haunted. Reinforcements of the Army is very good because most of your E-heroes are warriors. Dark Hole is important too.
