Deletion of MadHouse (duo)

Comment: It needs some work, that's for sure. But its current version cites quite a few notable and reliable Brazilian sources, so it passes . There are past versions of it adopting more appropriate tones, so CSD no longer applies. An article should only be deleted if it is beyond saving; doesn't seem to be the case here. An {{t|Advert}} tag would suffice, for now, until someone works on that promotional tone, which was added a couple of years ago by a probable COI account. They may have seriously compromised the text's tone, but the article itself is not to pay the price for that
