Good against...

 * Shadow Demon's entire kit counters Spectre, even her greatest strengths. If she would try to kill you with at any point of the game, there are a couple of rules to follow: either she's foolish enough to use  immediately, in which case you use the generic combo against her, or she doesn't in which case you can use  against the illusion to run away or kill it. The worst case is if you have to use disruption immediately to save your life, and she uses reality after that to chase you down with.


 * Odds are a Terrorblade in will die from your generic combo, even if he's smart enough to use  against one of the illusions when his hp runs low.


 * Alchemist is a well-known carrier, among other auras your illusions will benefit from. They also get the extra move speed and reduced BAT from his  and it's even better if you can catch him as his own rage is about to expire.

At level 3, with two points in, another point in  and a fifth unit to come next to your disruption, that's suddenly 500 physical damage +30%, or 650 damage, just from the Dazzle heal.

Others

If your ally has good stats and little raw damage/attack speed items, such as a, it's probably good. Be careful not to give the opponent a perfect setup for their spells.
 * However, since your illusions are so strong, never hesitate to use disruption on an ally's illusion as you're sure to get more damage out of it. The only exception to this is if the illusion would time out during the 2.5sec banish, as no illusions would pop out in this case.
