Forum:Missing the timing??

If I flip summon my des lacooda, to trigger its effect to draw a card, and my opponent chain TT to destroy all monsters on the field while my opponent has a Dimensional Alchemist on the field and a removed from play monster, will my opponent get a monster back through DA's effect?

What if my opponent uses DA's effect as priority when he normal summons DA,and then I activate TT, will my opponent get a monster via DA's effect?

DOes DA miss the timing or not in these scenarios?
