There needs to be a list of deck concepts.

[Demut]

You know, its really hard to come up with an unusual deck, when you have no idea whats been done before. There really needs to be a list of deck concepts and their popularity,

[ddevans96]

With the hundreds of decks that have been made?

[Ryli]

Feel free to go through all the decks and compile it in one post. I don't think it's something that anyone else will do, but as far as I'm aware there's nothing against small projects like this if you keep them tidy and organised.

Everything has been done before. Including all pillar decks. On a day of a patch that includes new cards, you'll see similar/same decks posted by several players.
Just have fun building decks regardless if its been done or not.

Perhaps, but I just spent all day making and testing in pvp light dualities with every other element. And posted them. I was trying to keep them unusual. But I'm pretty sure at least a few of them are usual.

A complete list of deck concepts would be difficult as there are so many possibilities but at the broadest level, most will probably fit into one (or more) of these categories:

Rush Deck:  Basically pure offensive deck designed to kill them before they kill you

Stall Deck:  Tries to delay, stop, or simply outheal your opponent's attack until you can either deck them out or achieve a certain winning combination

Burst Deck:  Somewhere in between the first 2, these will start off building up slowly, then suddenly drop large numbers of creatures or deal massive damage all at once to quickly finish your opponent off(includes most fractal decks)

Destruction/Denial Deck:  Tries to either destroy anything your opponent plays or prevent them from playing it in the first place by destroying quanta sources and/or stealing quanta, preventing them from drawing cards etc.

Mindgate Deck:  Uses your opponent's own deck against them

the real problem is cardpool
we have like what? a dozens from every element (+/- 3) to form decks
in the grand scheme of things, low amount of cards = not much variety

as for concept, hodari hit it right on
the 3 main concepts are rush/speed, stall, burst/charge
