Theorycrafting Slowdown Teams

I've been trying to figure out how to get high damage on the Archdemon.  Pursuing that, I was watching some youtube vids and I saw some guy do a great trick with a slowdown team.  It's worth mentioning, since I am sure I will need that eventually.

The problem I have had with slowdown (besides the fact that I don't want the crests on most of my heroes most of the time) is that I cannot get a boss slowed down enough to stop him from getting to his first target.  I have tried with Warlock/Revite 3 and Harpy Queen -- still not enough.  And that stopped me.

But this guy I saw was using just about the same trick I use against the Rage Goblin and Centaur Ruler -- which you can find elsewhere at this blog.  The trick is this: you put in a hero with Revive for the boss's initial target.  Then you pour in the rest of your heroes and hit Invincible.  (This guy didn't even do that, but he was facing an Archdemon and they don't do that much damage.  Also he probably had max this and that, which I don't.)  After the Invincible ends, of course the boss kills the initial target -- but then that target revives.  Meanwhile the boss has targeted some other hero, but he's been slowed to zero with 10 seconds of full amped up Slowdown hits and various slowing procs.  So he can't move at all.  Then you pound away for the remaining ~168 seconds, completely safe.

This won't actually work on the iOS Archdemon because he autoprocs (so far we've only seen the one which stuns).  But it would work on any other single boss.
