New to this game; what is the point?

Hello,

I've been playing this game for nearly a week now...but I just don't understand exactly what the goal is in this game? How is the economy? I enjoy this game for the art, but it seems that some cards are just impossible to get.

Battling is pointless , monsters are weak, knock back is abusable, using allies is simply OP, lack of diversity, Time elixirs are worth so much; which I just don't understand (please someone explain)

But then again, I am new...what exactly should I aim for?

Thanks

Was it truly needed to make the exact same thread in two different locations?
