Just started botting on a new account, and being a new account, it can't build 99% of the decks suggested here.
I mainly use this deck for farming the daily 30 wins, the golden hero and class quests.
For all new botters and accounts, I present the F2P Paladin Deck which, over 7 days of botting at Rank 20, has an average 62% WR.
I used the default AI and it does pretty well, excluding some misplays regarding shattered sun cleric being played
before another minion. (Maybe updated silverfish could solve these)

I would suggest selecting the 'Auto concede if last game won' option as well as 'Auto concede if opponent's class = Mage".
Since Mage battles tend to go for longer and victory is much harder, I suggest not playing against them.
As this is a F2P deck, please try it out and let me know how things work out for you.
Any suggestions on improving this deck using basic cards only would be welcome.
