A popular tool for tag clearing right now is Networking which is more efficient than Misdirection for clearing a single tag, as efficient with two, and increasingly less efficient as the number of tags increases (assuming equivalency of and ).
Obviously an important card on everyone's mind right now is Hard-Hitting News. Clearing the resulting 4 tags in one round, or simply avoiding a crippling tempo hit, can be critically important for certain decks. Without Misdirection you are paying 4 and 8 to clear the tags. With Misdirection installed, you are saving 2 and 4, and importantly need only have 2 as opposed to 8 in your pool at the start to recover in one round (->,->, use Misdirection). Note that with Magnum Opus installed, you can clear up to 4 tags in one round from 0, greatly reducing the efficacy of Breaking News/Closed Accounts combos. This compares favorably with Networking which requires 4 and 4 to recover
The fact that it is a program is nice because it can be tutored easily out of Shaper (even if you use Self-modifying Code to fetch it you are paying 2 less to clear all tags from Hard-Hitting News which may mess with the Corps math) and it is not susceptible to being trashed if a tag does land. Nonetheless, that's another 1 for your rig. I imagine this card will definitely see some play in Shaper at least considering it also saves 1 influence pip over Networking and doesn't need to be held in hand.
