Yes.

And It is the same pattern every time :

Raid event => Release of new raid card with Great damage skill + for the second half new raid card with x5-10 damages to the hidden boss.

Thos Great damages are only effective for the current raid bosses. After the event those cards, and  ALL the other raid cards deals Med damages to the bosses.
