Just make whatever decks you can, and let the bot farm for you. In terms of climbing ladder, I might wait a bit (couple more weeks) to figure out what the meta is, and build your deck out (presumably on Wild). Use Hsreply to look at the top decks and try to think through if the bot can play those decks for you. People also post decklists and configs on here, so it might be worth building towards one of the posted decks.
