Up until level 9 you can basically anything. For level 10 you have a little bit less freedom because you can have slot problems for very slot intensive decks.
The Batariel strategy is a speedrun strategy for some rPvE maps. You will have no issues beating any map with that if you play it correctly that is.
As you can win rPvE 9 with every orb combination it would be helpful to know what kind of orb combination you want to play. That is so i/we can give you more precise advise instead of just listing cards of possible decks - as there are so many viable ones
As you seem to be an beginner/advanced player (correct me if i am wrong here) i would probably reocmmend Fire Nature or Shadow Nature as good options for you. They tend to be decently quick, offer a decent amount of protection (heals) but not overly so like pure nature or Nature Frost.
You can however play anything else you want as mentioned above.
