That would limit the number of copies in the pool to 2. If you add it to:This card may be played with a starting company in lieu of a minor object.
then you have:reveal it when starting companies are determined as if it were a character
a- 2 copies max in the pool, as it must be treated as a minor object
b- revealed as a character, not as a permanent-event
That should solve the problem, I think.
PS: I'm not a fan of little corners of the wording, but "This card may be played with a starting company in lieu of a minor object". That "with" instead of "on" may also guive some guidance (because the first phrase on the card, the one you should abide to if you want to play it during the game, not at the draft, is "playable on a company").
