Can you do this? Play a Blast card then Direct Hit play a Blast card then another Direct Hit then another Blast card.

Can you use Evasive Action against a Fighter to stop damage to your Fighter?

Have a good day.

I don't see why you can't have a chain of blast-direct-blast-direct-blast...

Dunno about your evade question

Evasive Action can be used to cancel a SQUADRON card, as well as BLAST and DIRECT HIT cards, so you could use it to block a Fighter (or Bomber). SQUADRONS cancelled are returned to the player's hand however instead of discarded (though I think it's implied that they cannot be used again this turn).
