I had lots of fun with Masa proxy barracks shenanigans and while it may be what people call "cheese" it's a viable strategy with it's fair share of risks.

Spoilers of the match ahead, for those who care about it...

On game 7 Neeb sent 2 Oracles to harass Masa mineral line and it was GG from that point and I think this kind of harass would beat Masa strategy every time. Still, kudos for Neeb to realizing it on game 7 and executing it properly... I feel this was not a strategy he had planned and he adapted on the fly to counter the constant proxy bullshit Masa threw at him.

Now, if only Zerg had something like that to protect themselves from proxy cheese.... :(
