There is this thread with some basic decks

I don't really think they are the best possible but they are better than nothing.
Do you have an unlimited account?
If so you should have the bot create the best decks it can automatically.
If you don't have an unlimited account and want to farm gold to make a good collection I really think you shouldn't bother.
The free 2 hours daily isn't enough to farm gold just on basic decks.
I know that from personal experience.
I still use the free trial daily with some of the best decks and barely reach the 100 gold daily cap.
