Microbot Alpha: how far does it consider others Microbots?
Yes. All minions are considered Microbots. So everything that applies to Microbots applies to all your minions in play.

However, as included in the Pretty Pretty Smash Up rules, page 10:


  "A minion" or "minions" means any minions in play unless stated
  otherwise.


So minions in your discard pile are NOT affected.
