What happens if I chain Dust Tornado to Mountain while Umi is active?✓
Player A activates Mountain while Umi is active, and Player B chains Dust Tornado targeting Mountain.
Dust Tornado resolves first and destroys Mountain. Since Mountain never resolves, Umi remains active.
After an attack declaration chain resolves, can you activate other Battle Step cards?!
An attack is declared, Dust Tornado is activated, and it is negated by Solemn Judgment.
Yes. You may start additional chains in the Battle Step, but cards that require the attack declaration window (like Mirror Force) cannot be used again.

You must destroy 1 Spell or Trap Card on your opponent’s side of the field to be able to Set 1 Spell or Trap Card. If your opponent chains a card to destroy the target of "Dust Tornado", you cannot then Set a Spell or Trap Card because "Dust Tornado" did not destroy a Spell or Trap Card.
If your opponent activates the card targeted by "Dust Tornado" it is not negated, but is still destroyed by "Dust Tornado" so you may Set 1 Spell or Trap Card.
