I'm not familiar with all of them but one that I've noted is that the restriction is lifted if you eliminate a friend's Elite Guard encounter. Support might work too though I'm not entirely sure since by nature I'm also a hitter and most of my weak hits also finish as a result.

To simplify: Encounter an Elite Guard, find and finish a friend's Elite Guard, try searching for an Elite Guard again and repeat as desired. Given the rarity of SEG encounters, I'm not sure if the encounter chance would include them in the restriction lift but it could be possible.

Hmm I see, thanks for the info! Learned something new today.
