Unfortunately, no, the Hyperion PDD does not stop widow mines.
Maybe he meant the mines will attack the PDD?
No, I did mean “will the PDD stop widow mines”. But I guess it makes sense to ask - would PDD’s aggro widow mines? They aggro enemy units in general, widow mines shouldn’t be any different.
My go to for brutation has been Stetman P2 and once again he shines.
His lings tank the mines with the upgrade while Gary can solo most waves and clear the bases allowing to go fast.
I still have to loose a game with Stetman despite doing brutation under leveled.
User name does not check out.
There are a few games where I lived up to my name but thankfully not that many 
going with Abathur’s P2 for this one, lol.
On one of my runs, got an Artanis P3 ally. What’s the point of that? Fast clear expo and lose Guardian Shell for the whole mission? On a mutation with mag mines that can wipe away a decent chunk of your army? The maniacal archons don’t even last long enough to capture a lock or reliably clear the 1st lock.
I suppose they could have been used to trigger mines ahead of the army, but that wasn’t being done. And it would be an expensive use of SoA. A Zealot or Phoenix would’ve sufficed, and probably survived longer.
They can clear the first lock, and the attack wave to that lock, and have almost half their duration to spare. Someone just dropped the archons in a very bad location.
