Yes actually. Anything with Rock Blast, Skill Swap or Mummy and ecause this is Hackmons anything can hav Mummy in case anyone starts wondering.
This is what poses a threat to your strategy:
Any Pokemon @ ???
Rock Blast
OR
Anything with a base speed above 40 with some speed investment @ ???
-Any super-effective move
-Any priority super-effective move
Once Again
Any Pokemon with Mold Breaker @ ???
Any move that affects Ghost and Bug types.
Any Steel type with good defense @ Leftovers
This thing will resist an E-Speed and probably have a Rock-type move, so watch out for these kind of stuff.
That's all it needs to mess you up.
Other than that if you pull it off your guaranteed at least one kill.
How to survive
Baton Pass a Substitute onto this set and given the opponent doesn't have Mold Breaker or Rock Blast or both you can get 2-3 Pokemon down comfortably.
Another way to survive
Put some Defense EV's on him so he can survive the substitute, get a few Swords Dances up and ultimately sweep.
In the end it should look somewhat like this:
Shedinja @ Safety Goggles (only if you have a sub passer) / Focus Sash
252 Atk/252 Spd OR 128 Def/ 128 Sp. Def/ 128 Atk/ 128 Spd (I recommend anything with good bulk and has access to Cosic Power or Stockpile and Speed Boost for Baton Passing)
-Swords Dance
-Shadow Sneak
-Endeavour
-Extreme Speed
That's how to fix your strategy.
It may not end up perfect or take time but given you have the time and correct Pokemon to Baton Pass you can easily pull it off and as mentioned you can ultimately end up sweeping.
Hope I helped!
