You basically pick the deck that contains the free legend card that you want an extra copy of. IMO, arguably your gameplan is:
>Use my friend invite code to receive free gold: hqKVPhk
>spend your early game gold on packs (you probably want to max out the tutorials/AI battles/story mode for extra gold)
>post a screenshot of what legendary cards that you've managed to pull so that we can help you decide which PvP deck will be your breadwinner.
>grab whichever premade deck helps you assemble that breadwinner deck
>stick with your breadwinner and start hoarding gold in preparation for the next set.
