An Elemental Hyper Beam! or A Charmer's Call! (Sorry, no picture >.<)

Well maybe there should be a Trap or Spell card that relates to all of the charmers being on the field at the same time... maybe if at least 4 of them were on the field at the same time, all of the opponents cards on the field will be destroyed!

or

Another card which allows the special summoning of other charmers while one of them is on the field o.o; (setting up for the first card I was talking about )

anyone likeys?

Hmm, this sounds familiar. I think there are some in the charmer related section. I probably have some up.

Well currently there IS a card that kills your opponents field, Elemental Burst, but you need to TRIBUTE 1 each of FIRE, WIND, WATER and EARTH to use it, and you can't use it with Doriado, however you can with Fuh-Rin-Ka-Zan, but you can only take out your opponents Spell/Traps OR Monsters separately, instead of at the same time.

So...yeah. There are cards that are like that. But I just wish that there were more cards that catered to the use of attributes. Since most of the supports were used for elemental heroes and not the attributes specifically. I think that an attribute based support system is a long way from creation. (excluding the charmer traps)
