If Mirror Force is Solemned, can I still activate cards in the Battle Step afterward?!
Mirror Force is activated and negated by Solemn Judgment during the Battle Step.
Yes. You can still activate cards in the Battle Step, as long as they do not require 'when a monster declares an attack' timing.
If Stardust Dragon/Assault Mode tributes itself to negate Mirror Force and I chain War Chariot, does a Stardust still Summon?!
SD/Assault Mode activates to negate Mirror Force and War Chariot is chained.
No. Tributing for SD/Assault Mode is a cost. Since it is no longer on the field when Chariot resolves, it cannot Special Summon Stardust Dragon.
