quite a thing back to the old day where elf could rush down enemy leader before 7 turn, here are the deck my girlfriend own, it kind of outdated though.

this way of build I prefer, since most of peoples draft tons of neutral cards, those include earthshock orge which could hit enemy leader 3 dmg or 6 dmg if you used EP, this kind of normal neutral could replace the forest weakness like the high cost and need cards count for the effect to active, which are really huge deal when playing this class.
