TvP is hard. But I've heard a lot of anecdotes lately about Protoss being greedy and getting run over by Hellions (because they feel very safe with MSC). Bomber almost pulled something off on the map Bel'Shir Vestige vs. Rain the other day. (Note Bomber still lost but the idea of it worked well, he managed to inflict a lot of economic damage.)
The other thing I've seen work really well is the doom dropping into the main and sniping the Nexus. Something that I have seen happen a lot on maps like Star Station.
Mvp also used some sick timings in the past with marine tank that were really good, because they don't really expect it.
I used to do 11/11 rax in WOL (biggest lulz) against greedy Protoss but now with MSC that's not even an option.
