Welcome CarbonBit, I have a feeling you will be a great player. I encourage you to finish your Rol/Hope, make an upgraded t50 farmer and visit the elements chat from time to time. Veteran players usually put farm decks (18 pillars, 6 rare, 6 rare), so you can request any rare you need.
After that you will be able to make any non-upgraded deck you can desire and ou can have fun with the non-upgraded pvp events. Those are probably the greatest part of the game, especially that some of them offer in-game prizes!
Anyway, good luck and have fun.
