the most important thing is to pick stuff you are actually good at, will enjoy, and will get good grades in. Yes, you need to do 2 solid subjects, but you have to actually enjoy them. 'Blacklisted' subjects is a very misleading term...its not like theyre going to see Drama and be like 'nope they're not coming here', its just you need a couple of academic subjects in there too. I'm at oxford and have friends here who did art, film studies, sociology etc and they all got here despite everyone calling them 'soft' or 'blacklisted' subjects
