Here is a "KO-and-capture" scenario from Avengers #129 and Giant-Size Avengers #2 (both from Marvel, November 1974). A robot sent by "Kang the Conqueror" re-directs Scarlet Witch's hex, and sends bricks flying towards her, Mantis, and Agatha Harkness. The heroines are conked out cold! Those impacts from flying bricks tend to do that...

There are quite a number of scenes with Mantis and Scarlet Witch imprisoned in tubes, as well.
